All About Wire Wire feed stoppages and wire feed system malfunctions can adversely affect the welding arc and create irregularities that may weaken the weld bead. nesting, a tangle of wire that halts the wire from being fed, is a common problem. You can resolve nesting by flipping up the drive roll and pulling the wire back out of the gun.


achieved. Consequently, the best materials and welding methods have to be chosen. Besides giving details of recommended filler metals for all kinds of steels, this manual also gives assistance in selecting the optimum welding methods and techniques. The manual is based on over 70 years of experience in making, using and welding stainless steels.

While AWS ER70S-3 is an all-purpose wire, AWS ER70S-6 is suitable for welding dirty and rusty steel. The latter is more economical compared to the two, and you can use it for all types of steel welding. Also, vary the diameter of the wire based on the thickness of metal you are welding.

Joint Design and Fit-up Guidelines for Laser Welding

Figure 1: The rule of thu for joint fit-up for a butt joint is that the maximum gap should be less than 10% of the lowest sheet thickness. The maximum tolerance for misalignment of the laser beam to the weld joint for a 0.6 mm focused laser beam is 0.5 mm. Weld strength is proportional to weld depth.

ER70S-6 is generally used for mild steel welding. 4. ER70S-2 is highly recommended for welding 4130 chrome moly tubing in many appliions. 5. ER80S-D2 is recommended for welding 4130 chrome moly tubing if a higher strength, less ductile weld is required. If your weld will be heat treated to obtain optimum strength, then use a filler metal

Hardfacing - Wikipedia

Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and gas tungsten arc welding (TIG) welding. Powder metal alloys are used in (PTA) also called powder plasma welding and thermal spray processes like high

Fillet Weld Size - Rule of Thu - Welding, Bonding

May 14, 2002· "(a) for full strength welds, the leg of the fillet weld must be about 75% of the plate thickness." Here is my take for double fillet welded joints The effective throat of an equal leg fillet weld is .707 x leg size. .707 x .75t = about .53t. 2 equal leg fillet welds with leg sizes of 75% the thickness of the base metal would result in a fillet

What is optimum thickness of insulation? - Quora

May 14, 2018· The optimum thickness really depends on where you are placing insulation. If you’re referring to home insulation, check out the recommended R-values for each area of your home here: Chapter 7: Insulation - Better Insulating Your Home and Preventin


Apr 15, 1997· Innershield NR-211-MP E71T-11 Versatile wire suitable for all position welding of light gauge 14-15 steel or thin plate up to 1/2” (12.7mm). Low spatter and excellent weld appearance make it a favorite with operators. Innershield NR-212 E71TG-G A good choice for general purpose, all position welding…


The slag from the weld bead normally peels off on its own or removed with the help of a chipping hammer. The main limitations of SAW are plate thickness and position, because SAW is a high heat input and high deposition rate process. It is generally used to weld thicker section of steel over 6.4 mm, although welding of 1.6mm is also

Automatic Welding - an overview | ScienceDirect Topics

In order to measure the thickness, the wire was made saturated magnetically using DC exciting coil to increase the penetration depth of eddy current. To obtain optimum shielding, it is suggested that the welding torch gas cup be as large as possible. in A Practical Guide to TIG (GTA) Welding, 1991.
