Success Stories & Industrial Applications

Real-world implementations of our handheld laser welding solutions.

Air-Cooled Handheld Laser Welding

Stainless Steel Architectural Metal Contractors


Client Background

The client in this case is a mid-sized stainless steel architectural metalworks company that has long undertaken projects such as door frames, railings, stair handrails, and metal trim finishes.
As most projects involve on-site installation, working conditions are highly variable, schedules are tight, and appearance standards are high, making this an industry that relies heavily on the experience of skilled craftsmen.
Previously, TIG welding was the primary method used. However, exposed weld points, excessive spatter, and heavy indoor fumes often led to increased post-processing costs and could easily affect the consistency and overall appearance of the finished products.

Challenges Faced

  • High aesthetic requirements: Exposed weld seams and excessive spatter require extensive grinding and finishing, negatively impacting project timelines.
  • Labor shortages: TIG welding demands highly skilled welders, with long training periods and difficulty in controlling delivery schedules.
  • Heavy indoor fumes: In shopping malls and residential projects, TIG welding fumes often cause disruptions and lead to complaints.

Solution

Introduction of an Air-Cooled Handheld Laser Welding Machine

  • Lightweight, air-cooled design : Compact in size, making it ideal for highly mobile on-site construction work.
  • Fine weld seams with extremely low spatter : Smooth and clean welds significantly reduce the time required for post-weld polishing and grinding.
  • Low learning curve : New operators can become proficient within approximately 1–2 hours, eliminating heavy reliance on highly experienced welders.
  • Small heat-affected zone and minimal deformation : Delivers a noticeably improved appearance, especially for thin plates and stainless steel architectural components.

Implementation & Benefits

  • Significant improvement in the appearance of decorative welds.
  • Enhanced product consistency, resulting in fewer customer complaints and reduced rework rates.
  • Construction efficiency increased by 2–5 times.
  • On-site installation time greatly shortened, accelerating overall project schedules.
  • Post-processing costs reduced by 30–60%.
  • Less grinding time required, with material surfaces no longer blackening or deforming.
  • Greater workforce flexibility.
  • The company successfully enabled new hires to quickly take over on-site operations, effectively easing labor constraints.

Water-Cooled Handheld Laser Welding

Metal Fabrication Plant Production Upgrade


Client Background

The metal fabrication plant has approximately 40 employees and primarily manufactures stainless steel enclosures, aluminum alloy frames, and sheet metal structural components.
As orders continue to increase, the company must boost production capacity while maintaining high weld appearance quality.
Traditional TIG welding is slow, incurs high post-processing costs, and relies heavily on skilled technicians, which has become a major production bottleneck.

Challenges Faced

  • Insufficient production capacity: TIG welding is slow and unable to meet high-volume order demands.
  • Thin sheet deformation: Leads to scrap, especially pronounced in aluminum processing.
  • High post-processing costs: Extensive grinding and polishing result in wasted labor hours.
  • Inconsistent quality: Weld quality varies from one welder to another, making it difficult to maintain consistency.

Solution

  • Introduction of a Water-Cooled Handheld Laser Welding Machine
  • The water-cooling system enables long-duration continuous operation.
  • No power derating and no overheating, making it suitable for high-duty production lines.
  • Three-in-one functionality (welding + cutting + cleaning) improves production-line flexibility. 
  • A single machine can perform multiple processes, reducing equipment changeover time.
  • Improved weld consistency.
  • Concentrated and stable laser energy prevents burn-through on thin sheets
  • High-power options (1500W–3000W).
  • Capable of processing thinner materials while overcoming the limitations of traditional welding methods.

Implementation & Benefits

  • Welding efficiency increased by 2–10 times.
  • Production time significantly shortened, enhancing order fulfillment capacity.
  • Post-processing costs reduced by 30–70%.
  • Smooth weld seams, with grinding no longer a major bottleneck.
  • Lower scrap rates and improved material utilization.
  • Marked improvement in success rates for aluminum and thin-sheet welding.
  • Rapid onboarding of new operators, reducing reliance on highly skilled labor.
  • After implementation, processes that previously required 2–3 years of experience can now be mastered by new operators within one week.

Water-Cooled Handheld Laser Welding

Sheet Metal Fabrication Industry


Client Background

A small to mid-sized sheet metal fabrication company with approximately 30 employees primarily undertakes stainless steel and iron sheet welding, cutting, and customized processing orders. On-site operations rely mainly on **traditional TIG welding and distributed equipment.
As order volumes grow and delivery pressures increase, the company faces challenges such as insufficient welding manpower, long training periods, and difficulty controlling quality.
The client aims to introduce equipment that is easy to operate, highly efficient, and capable of integrating multiple processes, in order to improve overall sheet metal processing efficiency and on-site flexibility without significantly increasing labor, meeting the demands of future order growth.

Challenges Faced

  • Labor issues : Weld quality heavily depends on experienced welders, making it difficult for new employees to get up to speed quickly.
  • Lengthy post-weld processing : Uneven weld seams require additional grinding and leveling, increasing labor workload and putting pressure on delivery schedules.
  • Thin-sheet welding and heat management : Many sheet metal parts are thin and small, making them prone to deformation, burn-through, and long heat-cooling wait times during welding.
  • Frequent order changes : Long process changeover times make it difficult to quickly respond to urgent customer orders.

Solution

  • Sufficient strength
    The heat-affected zone, material deformation, and stress during laser welding are minimal, allowing the welded material to retain excellent mechanical properties—making it ideal for high-strength joints.
  • Improved efficiency
    Lowers the entry barrier for welding. Even when skilled technicians are stretched thin, inexperienced operators can quickly start welding. It also provides experienced welders with a more precise and manageable tool, giving them confidence to tackle complex welding tasks.
  • Precision components
    Capable of handling small and highly precise parts, allowing welding without damaging the base material. Particularly suitable for thin sheets and high-precision component fabrication.
  • Curved and contoured applications
    Excels at welding parts with curves or arcs, offering flexible and precise control. Enables high-quality welding on complex geometries, meeting diverse design requirements.

Implementation & Benefits

  • Optional dual wire-feed module:Can feed two welding wires simultaneously, effectively enhancing filler efficiency for large weld seams and improving joint strength and molten pool stability.
  • Integrated cooling and electronic control system: Equipped with rollers, making it suitable for in-plant maintenance or on-site construction.
  • Supports high thermal conductivity metals (such as copper and aluminum) and high-strength structural components (such as mold steel), meeting the welding requirements of various parts.
  • High weld seam flatness: Laser-welded components generally require only minimal finishing before proceeding to downstream processes such as painting or assembly.
  • Gap-filling and reinforcement for assembled parts with misalignment or uneven edges: Ideal for panel edging, enclosure side reinforcement, improving fitment and overall airtightness. In situations requiring medium-to-thick plate welding where the production line cannot achieve high-precision positioning, it serves as a highly flexible compensation technique.
