Advantages of the laser welding:
– punctual energy input, exactly localised, even in very fine structures.
– limitation of work piece deformation to very slight or none.
– high mechanical strength of welded seams.
– seams are slim and flat, their surface oxide-free.
– non-contact welding without effects of mechanical force on the work piece
– no edge burning
– excellent process control ensures constancy of quality in manufacturing.
Main types of wire:
01_9100
For the laser welding of the materials 1.2311, 1.2312, 1.2162, 1.2738 and for low-alloyed steels, like StE 355, 17Mn4, 15Mo3.
The weld can be eroded, structured, polished, chrome plated, etched, nitrated, and annealed.
Constituents: C – 0,10 %, Si – 0,60 %, Mn – 1,10 %, Mo – 0,50 %, Fe – Rest
01_9130 | 01_9160
Often used laser welding wire for repairing and changing at the contour with universal characteristics, also at unknown alloys. Free of cracks and incomplete fusion by multi- layer weldings. Tough welding material, good corrosion resistance, high wear resistance and toughness, for highly stressed hot working tools, which are subjected to high thermal and abrasive loads. The weld can be polished, heat treated, nitrated, chromplated, and CVD coated. Recommendation 01_9160: Using für mirror finish.
Constituents: C – 0,25 %, Si – 0,60 %, Mn – 0,70 %, Cr – 5,00 %, Mo – 4,00 %, Ti – 0,60 %, Fe -Rest
01_9200 | 01_9210
Laser welding wire used for highly wear resistant build-ups on machine parts and tools subject to heavy abrasion and compression combined with moderate impact at elevated temperatures. Low wear when using fiber-glass re-enforced plastics workable by grinding with tungs-ten carbide tools. By multilayer welding decking with 01_9650 or 03_9240 recommended. The weld is suitable for hardening, nitrifying, etching, polishing and chroming.
Recommendation 01_9210: Using für mirror finish.
Constituents: C – 0,35 %, Si – 0,30 %, Mn – 1,20 %, Cr – 7,00 %, Mo – 2,00 %, Ti – 0,30 %, Fe – Rest
01_9300
For the laser welding of press-, stamping- and cutting tools. The hard and tough weld deposit is very tough and has an excellent edge retention.
Constituents: C – 0,50 %, Si – 3,00 %, Mn – 0,50 %, Cr – 9,50 %, Fe – Rest
01_H13
