Product Information

* Gas tungsten arc welding (GTAW)* 

 

 

 

Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode is protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma.

 

GTAW is most commonly used to weld thin sections of stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than competing processes such as shielded metal arc welding and gas metal arc welding, allowing for stronger, higher quality welds. However, GTAW is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. A related process, plasma arc welding, uses a slightly different welding torch to create a more focused welding arc and as a result is often automated.

Company introduction

C&H Welding is an expert on the overlay based on special welding.

We are specialized in Corrosion resistance and Hard facing welding by using SMAW, GTAW, FCAW, GMAW, PTA welding processes. 

 

According to customer’s specification / ASME Sec.IX,

WPS(Welding Procedure Specification) development can be offered.

 

And in order to get high quality, after checking a result of sample that is tested exactly carried on with the valid welding processes, variables by produced WPS,

we perform welding after verifying the results to specify a welding range thereby work can be more effective and best condition.

 

It can be applied to various product such as Roller, Bucket, Cone crusher, shaft, Pressure vessel, tool, Gear, Tubesheet, Ring, Screw, Pipe, Elbow, Tee, Flange, Valve, etc., and various business fields such as steel making, heavy industry, shipbuilding, offshore plant, petrochemistry plant, etc., and it will bring many advantages for cost reduction, long maintenance period, and quality improve.

  

C&H Welding will do our best to realize customers satisfaction and make the best quality products on the basis of overlay welding technology.
