[MW:9194] RE: 9188] Regarding GTAW Welding Machine

By Materials & Welding

Dear sir,

There are two options for your applications.

1.       Buy a 200 Amps Invertor Based welding machine. For 6 mm plate, current requirement will be about 120- 150 Amp. Therefore it should be suitable for you. However there is one more factor which you should consider and that is the duty cycle. In case your requirement is continuous welding, the second alternative is :

2.       Go for a 400 Amps TIG welding machine. It will be suitable for your present application as well as higher thickness which you may come across in future.

Subject: [MW:9188] Regarding GTAW Welding Machine

 

Dear All,

 

 

We are going to weld 4 mm / 6 mm stainless steel plate.Filler wire dia is 2.4 mm and tungsten electrode dia is 1.6 mm.

 

for welding machine what should be the output current range and maximum continuous current at 100% duty cycle. please suggest me which welding machine is best for this application .

 

we are manufacturing this product in india.

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

By Materials & Welding
Hi,  You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this.  Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime.  Again, these simulated no. Of cycles shall be specified in MTC.  The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case).  One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example.  In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...
