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 difference between E71T-11 and E71T-GS?

T-11 wire actually has a AWS specification, is multi-pass rated and better suited to thicker materials. T-GS wire is single pass rated, better suited to thinner materials, does ok even if surface is coated, rust, galvanized, painted, etc.

What does E71T-11 stand for?

Description: E71T-11 is a self-shielding flux cored wire designed for single or multi pass welding while having a spray type transfer commonly used for carbon/mild steels less than ¾” thick. This all position wire can be used in the field where shielding gases are not practical.

What is E71T wire?

Description: E71T-11 Welding Wire is a general-purpose self-shielded tubular wire that is designed for welding thin guage mild or galvanized steel. Great for welding outdoors or in drafty conditions, this all-position wire also provides very low spatter levels, resulting in a weld bead that is excellent in appearance.

What is E71T-GS used for?

E71T-GS is a carbon steel, flux cored electrode for use without an external shielding gas. This electrode is intended for welding thin-gauge carbon steel, ranging from 3/16” to 22 gauge.

What is a single pass welding wire?

These single pass electrodes are highly alloyed chemicals that clean ( like for galvanized ) so you can weld on crap at high speed ( fast your move less time for cleaning so you need to put more cleaners in ).

What GS welding?

CEPL ME71T-GS is a flux cored, self-shielded wire designed for welding applications where the use of an external shielding gas is not practical.

Does flux core welding need gas?

Self-shielding flux- cored wire does not require external shielding gas because the weld pool is protected by gas generated when flux from the wire is burned. As a result, self-shielding flux-cored wire is more portable because it does not require an external gas tank.

What does JH8 after an Fcaw electrode designation indicate?

JH8 – This optional code designates the maximum amount of diffusible hydrogen the wire can contain.

Which is better.030 or.035 flux core wire?

The thing is a lot of times the machine is not powerful enough to burn thicker wires than 0.30. The 0.35 wire has much more filler in it and it also covers the bead better with flux. So in most cases, mostly depending on your machine, the. 035 would be my choice.

How do you read a welding wire number?

The letter “E” indicates an electrode. The first two digits represent the resulting weld’s minimum tensile strength, measured in pounds per square inch (psi). For example, the number 70 in a E7018 electrode indicates that the electrode will produce a weld bead with a minimum tensile strength of 70,000 psi.

What does DC reverse polarity mean?

Direct current (DC) flows in one direction, resulting in a constant polarity. With few exceptions, electrode-positive (reversed polarity) results in deeper penetration. Electrode-negative (straight polarity) results in faster melt-off of the electrode and, therefore, faster deposition rate.

Is flux core welding any good?

Flux-core welding offers greater penetration, which is good for working with thicker joints. It also allows the welder to travel in all directions and hold the torch in a number of directions. This makes it particularly suited to general repairs, shipbuilding, and other types of manufacturing.

What do the numbers mean on welding wire?

The first two digits of a 4-digit number and the first three digits of a 5-digit number stand for tensile strength. The next to last digit indicates position. So, “1” stands for an all position electrode, “2” for a flat and horizontal electrode, and “4” for a flat, horizontal, vertical down and overhead electrode.

Do you push or pull flux core?

With flux-cored welding, you should always use a drag (pull) technique, in which the tip of the welding gun is being pointed back at the weld pool and dragged away from the completed weld. An easy rule of thumb for remembering whether to use a push or drag (backhand) technique is: “If there’s slag, you drag.”
