Titanium welding wire Notes

1, construction workers and welders should wear clean white fine gauze gloves (non-wearing cotton gloves).
2, the processing of non-pads touch and contact with iron materials.
3, welding work as possible in the room, the ambient wind speed should ≤0.5m / s, avoid the draft affected.
4, titanium welding wire should be as short arc welding using welding, using a small welding heat input welding nozzle and retaining 70 ~ 80-degree angle.
5, taking over the tack welding, the butt gap is generally about 0.5mm.
6, each weld seam should be as a complete, must be connected to the welding of the weld, before welding should be clean interface, welding meat lap length of 10 ~ 15mm.
7, titanium spring wire welding, torch should not side to side, can not be removed from the molten end of the wire gas shielded area .
8, the welding arc should be aspirated in advance, can not lift immediately when the torch arc, gas should be postponed until the temperature dropped to below 250 ℃.
9, medical titanium plate gas drag cover the distance of the torch should be the shortest better, and We seek to minimize the contact gap wall. When the tube butt welding, forming side welding in order to achieve the requirements, the welding carried out twice: once for the back cover welding (welding back when you can not fill material) and the other for the forming welding. When the multi-layer welding, must wait before a weld to cool completely, then welded to the next bead.
