First, Butt-weld is short for a butt groove. Welding in a butt-groove starts at the throat of the butt-groove. The first weld point could be a tack-weld: holding the two materials to be welded together. The throat is measured and filler metal and electrode are determined to create the root pass.
It is one way to "Stress Relieve" the weld joint. As the weld metal metal cools it contracts and hammering on the weld expands it. On thick sections it is done after every layer of weld. Often used when welding cast iron or other metals with a low COE (Coefficient of Expansion).
The required size for a seal weld per AISC is eighteen foot length. AISC also specifies minimum weld size based on the thicknesses of the members joined.
wildly welding main pipe the are fillet weld or butweld
The difference between a full penetration weld and a deep penetration weld is the depth at which the metals being joined are actually joined. A full penetration weld is a slight puncture only to heat the two metals and join them. A deep penetration weld is a deeper hole puncture that is held and a metal wire is melted to join the metals.
Full penetration.
Lack of fusion and inadequate penetration.
Without knowing exactly which Code or industry this applies to, I'll give it a shot using AWS D1.1 standards. The standard flare-groove detail is P10 indicating that it is a PJP (partial joint penetration) weld. If a weld size is not indicated, it is assumed it is a full thickness weld and I believe this is where the confusion comes in. It's a partial penetration with full thickness and that's where the argument starts. This weld could be used as a full penetration weld (and held to that testing criteria) but the detailer must be specific about the intentions, particularly if it is used in a critical joint.
tell me full penetration joint process
To measure penetration of a weld, one must cut and etch the weld, preferably on a test coupon. Etching is just using an acid that will discolor the weld metal so that there is a visible difference between the weld metal and the base metal. Once the acid has taken affect, one can measure the weld using calipers or a similar measuring device.
A Backgouge consists of preparation of the second side of full penetration welds to the extent necessary to permit the proper deposition of weld metal.
a weld that does exactly what it sounds like, the molten metal that is created when welding is created all the way through the materials being welded. for example, if it is a 1/16th inch steel plate, a full penetration weld would create a molten bead from the front to the back of the plate. A full pin weld is when u have a bevel on one side that u weld first flip it over arc air gouge the other side and weld that side up
it will lead to increased amperage and decreased volts. more penetration and a faster deposition rate
