304 stainless steel welding procedure



304 Stainless Steel Welding Procedure

Welding austenitic stainless steels to carbon and low alloy steels are Weld procedures using filler (consumable) enable better control of joint corrosion resistance and austenitic stainless steel grades such as 1.4301 (304) or 1.4401 (316).

Stainless Steel Welding Procedures - Aufhauser Corp.

Stainless steel base metals are grouped primarily into three classes depending on their crystal structure; austenitic (such as 302, 304, 308, 316, etc.), martensitic (such as 410, and 416), and ferritic (such as 409, and 430). Below is a basic step by step guide to follow when welding stainless steel.

TIG WELDING 304 STAINLESS - American Welding Society

Sep 29, 2005 · A 304 or a 304L, with allowable amounts of sulfur, very seldom have any detrimental affects on the welding of this grade of stainless steel. The only "bad" thing of sulfur in a 304 grade, is the slight possibility of hot cracking, but when was the last time anyone has experienced that problem with a 304 using acceptable welding procedures?

StoneCold; GTAW welding of stainless steel socket welds is very common. The filler metal selection is fine, ER308L is typically used. The key to avoid cracking in the weld root is to assure you have an adequate gap on fit-up (1/16" min).The other key is have a material a bit of ferrite on solidification. Just about any 3XX filler will meet that criteria. The only real problem is that they are using filler that costs a lot more than they need. = = = = = = = = = = = = = = = = = = = = Rust never sleeps Neither should your protection trent-tube/contact/Tech_Assist.cfmEdstainless/Metengr, would you recommend minimum two pass fillets?? In my understanding, GTAW is "better" for welding stainless because the heat input can be better controlled. Thing is, where I work, it's our "common wisdom" to be suspect on welder GTAW technique with respect to root penetration and sidewall fusion, and will radiograph greater than minimum % of GTAW'd weld. In the case of SW's, we look both for minimum gap and for tell tail LOF. Cheers RobGTAW welding has either less or more heat input control depending on your definition of control. If by control, you mean that the welder has more flexibility, then yes, there is more control with GTAW. If by control, you mean that a heat input per inch of weld can be controlled better, then no. You can get carried away with high heat input with GTAW welding if you are not set up right, or the welder is not experienced or does not use good technique. That is because heat input is indepenant of filler metal addition. In SMAW for instance, you are guaranteed that two beads of the same size were made with approximately the same heat input. Not so with GTAW. It is also true that with improper welding techniques, it can be difficult to get complete penetration to the root of a fillet weld, but in my experience, GTAW welds should have less defects per inch of weld than most other processes if done properly.ER316L is often used to weld 304L material and can provide superior corrosion resistance; however, in some corrosive environments it may be highly detrimental (most notably in environments subject to metal dusting of 316). ER308 is the more economical choice especially when taking into account today's high molybdenum cost. We almost exclusively weld stainless steel sockets with the GTAW process. The leak incidence using SMAW was simply too high due to poor welding technique at the tie-in locations.1Were they following a WPS and what did it call out for filler?We weld 304L socket welds with ER308L filler metal, unless the owner/engineer requires ER316L and we have had a number of instances where it was so defined. Written procedures, qualified per ASME IX are used. The problem with SMAW simply invoves welder technique and proper welder training to assure sound welds; unfortunately, field management will not provide the appropriate training because "its just a socket weld and any qualified welder can do it." All of our GTAW welders are qualified for "open root" pipe welding and have no problem making sound, leak tight socket welds. Well trained welders make sound welds repeatedly.Field welding 316 and passivationFeb 14, 2010316 SS pipe welding to carbon steelNov 15, 2007See more results
