Note the use of titanium welding wire

1, construction workers and welders should wear clean white fine gauze gloves (non-wearing cotton gloves).
2, the weld area treated and non-contact touch iron items.
3, welding work as much as possible in titanium bar supplier the room, the ambient wind speed should ≤0.5m / s, avoid the drafts affected.
4, welding wire when titanium welding with short arc welding, the use of small heat input welding, the welding nozzle and the holding angle of 70 to 80 degrees.
5, taking over the position welding,grade 3 titanium butt gap is generally about 0.5mm.
6, each weld should be possible once finished welding, seam welding must be connected before the weld interface should be clean, weld meat lap length is 10 ~ 15mm.
7, when the welding torch should not swing around, wire melting end not out of gas reserves.
8, ahead of the welding arc when aspirated, not lifted immediately when the torch extinction, should be delayed gas, until the temperature drops below 250 ℃.
9, a gas mask and protective distance drag the torch should be the shortest better,Titanium tube supplier seek contact with the wall of the smallest gap. When the tube butt welding, forming side welding in order to achieve the requirements of the welding carried out twice: once for the back cover welding (welding when you can not back fill material), and another for forming welding. When the multi-layer welding, must wait before a weld completely cooled, then the next weld bead.

titanium wires Introduction

In the oxygen-rich conditions must take into account the effects of oxygen absorption hardening depth .  Only under conditions of thin layer thickness in a vacuum or in argon - methane atmosphere,grade 3 titanium it may penetrate the toner to form a sufficient adhesive strength as compared with this, using a gas  agent may form hard and particularly good adhesion titanium carbide hardened layer. While the: and 10201: conditions at temperatures between formation and hardening exhibition in between.medical titanium bar With increasing thickness of the titanium carbide layer becomes more brittle and tend to peel t To avoid leaving alkyl decomposition of carbon inclusions invasion of titanium carbide layer should be about 2% volume fraction of the provisions Rui alkyl dose additive gas  in an inert gas. When using propane, methane and the use of additives on the formation of  when low surface hardness. When the adhesive force reaches Wu Mao  conditions when using propane gas although the measured thickness of the hardened layer is very thin, but it has the best wear resistance. Absorption of hydrogen in the gas  agent type conditions using either, but had to remove it again when the vacuum annealing
