Re: [MW:5243] Use of MIG filler wire as a TIG welding filler wire

By Materials & Welding
Dear Mr. Hitesh,
 
The TIG and MIG filler wires are  manufactured as per same SFA specification only difference is that you get in spool form for MIG welding and cut length form for TIG welding.  You can use the MIG wire for TIG welding with out any deviation in properties.

Dear friends,


i am going to use below ER316LMn filler wire for SS316L. (working condition 4.5K ( -269 'C ) temp.)

ER316LMn filler wire available for TIG & MIG welding. i want to use 1.2 mm dia. filler wire for TIG welding but 1.2 mm dia. not available for TIG welding. 

as 1.2 mm dia. filler available in MIG welding. filler wire mfg. given property for ER316LMn listed below for GTAW & GMAW.

if i want to use MIG filler wire for TIG welding , can I get TIG welding property listed below.

Please give your valuable suggestions.

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...
