Which is the best welding process for stainless steel?
Most stainless steels are considered to have good weldability and may be welded by several welding processes including the arc welding processes, resistance welding, electron and laser beam welding, friction welding and brazing. For any of these processes, joint surfaces and any filler metal must be clean.See all results for this questionWhen to place the weld symbol above or below the reference line?The weld symbol may also be placed above the reference line, rather than below it. This placement is important. When the weld symbol hangs below the reference line, it indicates that the weld must be performed on the arrow side of the joint. For example, In the next drawing, a fillet weld is specified on the arrow side.See all results for this questionWhat's the difference between DC and DC-negative welding?With most arc welding processes, DC+ (direct current electrode positive) polarity produces more weld penetration, because more arc energy is focused into the base plate. Conversely, DC- (direct current electrode negative) polarity produces less weld penetration, because more arc energy is focused into the electrode and not into the base plate.See all results for this question
Welding Symbols - The Basics - Welders Universe
The welding symbol has an arrow, which points to the location on the drawing where a weld is required. The arrow is attached to a leader line that intersects with a horizontal reference line. Finally, theres a tail at the opposite end of the reference line that forks off in two directions. The tail is optional and needed only for special instructions.See more on weldersuniverse pa c degree Strip surfacing weldingWelding Jackets | Tillman | Miller | Weldx | Indura pa c degree Strip surfacing weldingWelding Jackets from Miller and J Tillman - Safety Wear Never Looked So Good.

If you look at an end slice of each size wire, the smaller diameter has less cross sectional area than the larger diameter.

Characteristic parameters of the submerged-arc and RES strip weld-surfacing processes. Because of their economic advantages, the ease of handling, the high degree of automation, and low cost of acquisition for the necessary equipment, these weld-surfacing processes have become well established long ago wherever claddings must be applied to large surface areas.Stainless Steels Welding Guide - Lincoln Electricresistance welding, lower current can be used because resistivity is higher.

How does current affect the degree of weld penetration?
The welding variable that has the greatest effect on the degree of weld penetration is current (measured in amperage or amps). Quite simply, as welding current increases (i.e., more amperage), weld penetration increases and as welding current decreases (i.e., less amperage), weld penetration decreases.See all results for this questionHardfacing Consumables | Alloys InternationalApplications include: Shear blades, forging dies, runways, cams, and slides.
