What does ER70S-6 wire classification mean?
What does ER70S-6 wire classification mean?
As an example, for a commonly used solid wire — AWS ER70S-6 — the “ER” indicates that the filler metal is an electrode or rod; the “70” signifies that it has a tensile strength of 70,000 pounds per square inch (psi); and the “S” means that it is a solid wire.
What is E71T-GS welding wire used for?
This E71T-GS Self flux-core welding wire for mild steel is ideal for all-position welding, and best suited for single pass applications with high travel speed.
What is E71T wire?
E71T-11 is a self-shielding, all-position flux cored wire for single or multi-pass welds on mild or galvanized steel. This wire is a general purpose wire designed for light fabrication and is good for single pass on thinner gauged material or limited multi-pass on thicker sections.
What is E71T-11 wire used for?
Product Description. E71T-11 is a self-shielding flux cored wire used for welding carbon steels. It does not require a shielding gas and can be used in limited multi-pass welding operations.
What does the 70 stand for in ER70S-3?
70,000 psi tensile strength
For example, ER70S-3 indicates an electrode or welding rod (ER) that will produce weld metal of a minimum 70,000 psi tensile strength (70); is a solid bare wire or welding rod (S); of a specific chemical composition (3) as shown in Figure 5.
What does E71T-1 mean?
7.6.0.3 As an example, the designation E71T-1 indicates an electrode (E) that will pro- duce weld metal of a minimum 72,000 psi ultimate tensile strength (7), may be used for welding in all positions (1), is a flux cored electrode (T), is a multipass gas shielded type for operation on direct current, reverse polarity ( …
What is the polarity of E71T-1?
The E71T-1C can be used only with DCEP polarity.
What is E71T-1 used for?
This electrode is developed specifically for enhanced welder appeal and exceptional weldability at both high and low end parameters. It is ideal for use in general fabrication, structural steel, construction equipment, railcar fabrication and shipbuilding.
What do the numbers on MIG wire mean?
The “E” indicates an arc welding electrode. The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength. For example, E6010 means 60,000 pounds per square inch (PSI) tensile strength and E10018 means 100,000 psi tensile strength.
What wire do I use for MIG welding?
MIG welding wire is primarily made of base metal. It may also include manganese, titanium, and silicon (residue of which can often be seen after welding). The wire is typically coated in copper which in addition to helping reduce oxidization during welding, can prevent the wire from rusting too.
