Why Copper to Aluminium Welding Is Difficult Electrical engineering loves the copper-to-aluminium joint: busbars meet aluminium housings, transformer terminals meet aluminium cable, battery packs mix copper interconnects with aluminium cooling plates. The combination saves weight and money - and it ...

Delivery and Installation Milestones A welding machine is only a product until it is installed; it becomes an asset on the day it produces its first qualified weld in the customer’s workshop. This update summarises the delivery and installation milestones recently completed across the PDKJ laser and ...

Zinc Coated Steel Spot Welding: Spatter and Electrode Life Galvanised steel is the backbone of appliance and construction sheet work, and it is also the material that quietly wrecks spot welding schedules. The same coating that protects the panel for twenty years attacks the welding process for ...

Certification and Third-Party Testing Progress Update Certification rarely makes an exciting headline, but for anyone buying welding equipment across borders it decides how smoothly the machine clears customs, how it scores in a tender, and how it survives an end-customer audit. This is a short ...

Laser Welder Daily and Weekly Maintenance Checklist A laser welding machine rarely fails without warning. It fades: power drops a little, spatter increases, the weld starts to look different from last month, and then an alarm stops production on the worst possible day. Nearly all of that traces back ...

Why Copper Busbar Spot Welds Fail: Root Causes and How to Fix Them Copper is simultaneously the best and the worst material for resistance welding. Its electrical conductivity is exactly why it is used for busbars, and exactly why it resists welding: most of the current takes the path of least ...

Why Does Laser Welding Warp Stainless Steel Thin Sheets? Stainless steel is one of the best materials for liquid cooling plates, manifolds, food equipment and medical housings, and it is also one of the easiest to deform. Put a laser weld into a 1 mm stainless sheet without controlling the process ...
