Welding and Cutting

Certain things come quickly to mind. The machines are cheaper than those used for most other processes. Some machines are engine driven (gasoline or diesel) making them useful at locations where there is no electricity (such as pipe lines). Almost any kind of metal can be welded as a large variety of electrodes are available. It is more portable cause you don't have to bring the machine to the work site, only the welding lead/cable. Gas coverage of the weld puddle is provided by the electrode coating. This eliminates the need to purchase gasses in cylinders, another cost savings. A wide variety of metal thicknesses can be welded by selecting the electrode size (diameter).

1/16 or an 1/8, usually an 1/8 and usually used in 6010 welding processes

Correct current,travel speed, electrode angle, arc length

To prevent welding related injuries always wear complete PPE or personal protective equipment. ❤️

When any material is welded it is melted. To join two pieces the edges are melted and allowed to fuse together or a filler is added, usually of the same material.

Cubic millimeter is not an area, it is a volume.

In any case, you would need some information about how large an area would be covered by every welding electrode.

Canadian Standard Association, Standard W59, covers welding requirements for carbon and low-alloy welded steel construction

cjp =complete joint penetration

typ =typical

DCEN means Direct Current Electrode Negative. Hook the welding cable to the Positive connection (+) on the machine, the ground cable to the Negative connection (-) Electricity travels from Negative pole to Positive pole.

PPA in welding refers to "Plasma-Powered Arc," a technique that utilizes a plasma arc to melt and fuse materials. It is often employed in high-precision applications and can be used for welding a variety of metals. The process offers advantages such as deeper penetration and improved control over the heat input, resulting in better weld quality. PPA is particularly effective for thin materials and in situations where a clean, precise weld is essential.

Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.

A good weld is characterized by strong fusion between the materials being joined, with minimal defects such as porosity, cracks, or inclusions, ensuring structural integrity and durability. A finish weld, on the other hand, is the final weld made in a joint or assembly, often designed to meet specific aesthetic or functional requirements, ensuring a smooth and uniform surface. Both types of welds are crucial for achieving the desired performance and appearance in fabricated structures.

It can be either including the wire in MIG (GMAW). In stick (SMAW) the electrode. Sometimes the coating adds small amounts of filler.

I believe you are confused. The number reading on the top of the welding electrode is simply an indication of the characteristics of that welding rod. Ex. 6013 means 60 thousands pounds of tensile strength per square inch,1 indicates that is an all position rod, and 3 is the mineral compound of the rod. Hints 6013. The welding rod size is indicated in fractions of an inch. Ex. 1/16, 5/64, 3/32, 1/8, 5/32 etc... Hope this has been helpful to you. Refer to the American Welding Society for further information.

we will have straight polarity and reverse polarity,we can produce the weld with good quality

D C Reverse (Electrode Positive) is recommended.

A base metal is also called the Parent metal. It is that metal in the welding practice that has been cut by the various forms of cutting, then prepared and is to be welded. Welding is performed to join one section of the base metal to another section of base metal by means of the various welding processes, e.g. SMAW(Shielded Metal Arc Welding) where welding welding rods are used, GTAW(Gas Tungsten Arc Welding) where Tig wire is used, FCAW(Flux Cored Arc Welding) etc. The welding rods, the TIG wires etc are called the filler metals, for they fill the weld gaps by depositing their molten-state weld metals.

Grind the surface of GI pipe lightly to remove the skin which is about 0.1 to 0.2 mm, than weld the MS pipe as per the wall thickness and use accordingly the welding rod at the required gauge / Dia of the welding rod. this works fine.

Hyperbeam will weld anything!

Oxygen is used as active gas during MIG welding, spray transfer. It increases penetration and travel speeds. It is used only is small amounts though ususally 1%-5%.

The question mentioned "gas" welding, not any form of electric-arc process, and in oxy-acetylene and oxy-hydrogen welding the oxygen is necessary to raise the fuel-burning temperature to above the melting-point of steel.

welding is a process which joins two dissimilar metals........ Actually it is more than that. Welding is a process that involves the application of heat to either add more material or join pcs. together. It is not used just for metals (dissimilar or not) but glass, plastics and more. The pcs. to be welded must melt in order for it to be called welding. Soldering, silver soldering, and brazing are comparable to glueing.

Double Sub-merged Arc Welding usually associated with spiral welded pipe. The welding arc is submerged in flux to protect from air impurities, this process is done on both the id and od seperately hence double submerged.
