What does CJP Bot Weld type means?
cjp =complete joint penetration typ =typical
Butt-weld and grrove weld?
Butt weld and groove weld are two common types of weld joints used in welding processes. A butt weld is a type of weld where two pieces of metal are joined together along their edges in a single plane, creating a smooth, flush surface. On the other hand, a groove weld is a type of weld where a groove or channel is created in one or both of the pieces being joined, and the filler material is deposited into the groove to create the weld. Both types of weld joints are used in various applications depending on the specific requirements of the project.
What is peening in welding?
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).
Is there required size for a seal weld per AISC?
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.
What is the filet weld size required for weldolets to main pipe joint?
wildly welding main pipe the are fillet weld or butweld
Difference between Full Penetration weld Deep Penetration weld?
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.
What effects does shortening the electrode extension have on weld penetration?
Shortening the electrode extension typically reduces weld penetration. This is because a shorter electrode extension results in a smaller arc length, which reduces the heat input into the weld and leads to less penetration. It is important to maintain the proper electrode extension to achieve the desired weld penetration.
If the weld does not combine with another weld or the base metal it is referred to as?
Lack of fusion and inadequate penetration.
What is partial penetration joint?
A partial penetration joint is a type of weld joint where the weld does not fully penetrate through the thickness of the materials being joined. This results in the weld metal being only partially through the joint rather than completely through. It is often used when full penetration is not required for the application.
Is a flare groove weld considered a partial penetration weld?
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.
What is the difference between Full-penetration butt welds and filet butt weld?
tell me full penetration joint process
How do you measure penetration in welding?
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.
Is lack of penetration the same as lack of fusion?
No, lack of penetration and lack of fusion are two different welding defects. Lack of penetration occurs when the weld metal does not extend fully into the joint, resulting in an incomplete weld. Lack of fusion, on the other hand, occurs when the weld metal does not fuse completely with the base metal or the previous weld pass.
Why must the current be adjusted for a particular welding operation?
The current must be adjusted for a particular welding operation to ensure proper penetration, heat input, and weld quality. Different materials, thicknesses, and welding positions require different levels of current to achieve the desired results. Failure to adjust the current can result in poor weld quality, lack of penetration, or material damage.
What is a weld backgouge?
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.
What is a penetration weld?
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
What is the effect on the weld if the electrode is held to closely to material being weld?
it will lead to increased amperage and decreased volts. more penetration and a faster deposition rate
