Lincoln L-50 mig wire

How does L-50 compare to L-56 regarding how the wire flows?Last edited by cope; 07-31-2014 at 11:48 AM.

Reply:Originally Posted by DanBoth wires contain de-oxidizers in their chemical compostion. The difference is that L-56 contains a high level of de-oxidizers then L-50. Alan (Cope), I've never ran an ER70S-3 wire  (L-50). All documentation I have on the different wire states that ER70S-3 will produce a less fluid weld puddle then ER70S-6. Some info I have is also makings it sound like ER70S-3 might produce a crisper arc then ER70S-6.

Reply:The choice of s-3 is usually specific based on need.Just speaking mig it's a more sluggish puddle with gas flux - open arc (short circuit), it needs a lot of Co2 if your steel has some scale or heavy oxidation. With spray arc it goes nearly as well as s-2 for appearance and is often used for multipass on heavy section. That's my take on what the weldor sees. If you are using Lincoln brand from Cleveland the s-3 (L50) feeds nearly as well as the s-6 (L56), both are very good with wire feeders.Structural and SAE guys often use it to get a DROP in mechanicals to avoid an overmatch condition as much as they can. That may sound funny but trying to drive the yeild point down to the mid 50'sksi has some real benefits if your parent material has a lower yield and tensile strength. If you PWHT you can get close to 50ksi yield and 70ksi tensile with very high charpy numbers, even with 100% Co2. The only fillers that you can get softer welds with are Lincoln L60 (EL12 sub-arc) and Lincoln L-S3 (EH12K sub-arc), but the smallest EL12 is 5/64" wire and the smallest EH12K is 1/8" wire so you won't be using them with a normal mig process.Matt
