Very likely to leak, zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.
minus weld gaps and takeoffs from total then multiply for angle.
Threading joint, weld joint, Flanges joint
Too long an arc length allows the arc to wander creating a poorly shaped weld. The slag is usually too thin and can allow Oxygen in the air to attack the molten puddle which causes Porosity in the weld. Too short an arc length buries the slag and creates less heat which traps the slag and impurities. Keep in mind that electrode coatings help determine the correct arc length.
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.
Weld mapping are visible marks that are seen on metal welded parts. Either they are welded together or repaired and sometimes you can tell who welded it, and when the weld was placed. Weld mapping is the process of assigning information to a weld joint to enable easy identification of its design (WPS), production (welders, their qualifications, date welded), quality (visual inspection, NDT) and traceability (heat numbers of materials joined & welding consumables). Weld mapping should also incorporate a pictorial identification to represent the weld number on the fabrication drawing, in case the designer does not nominate a weld number. You can use online weld mapping software such as Smart Welding Manager to create weld maps that provide 100% traceability as well as a pictorial representation.
you could weld up the back doors but it will still not look like a 2 door.
There is no such thing as a weld map. However a world map is a map that shows all the continents, oceans, cities and countries in the world. The world map is used in teaching, and you will also find the world map on a globe that spins.
The simplest answer is that working to a standard means that anyone can read the drawing. If there is no standard the symbols used on the drawing (weld type and size, surface finish, even the dimensioning of the components) would vary from one drawing (or draughtsperson) to another and cause confusion. Engineering drawings use a large number of symbols to denote operations and instructions (which reduces the time taken to draw them and the size of "paper" they're drawn on). Imagine the potential problems if one person used a symbol to mean "weld" and another one used the same (or similar) symbol to mean "do not weld".
like a spot weld, you don't weld 100 percent until it's all together and everything is square
Yes..look up alumaloy welding rods
There are 4 basics to producing a good weld bead. Correct #1 Amperage #2 Electrode Angle #3 Arc Length #4 Travel Speed Factor in electrode manipulation in some cases.
seam welding is a process that produces a weld at the faying surfaces of two similar metals where its used depends on which metal you look to weld
Pick up a rock and look under erneath it and maybe you find the answer
a draftsman / a person who makes a technical drawing for steel structure department with the help of DIM, notes, weld symbols, etc.. & part in to mainly two type that is GA for engineer & Shop drawing Fabricator. that's called structural draftsman.
FP on a weld symbol stands for "Fillet weld all around." This means that a fillet weld is required to be made on all sides of the joint where the symbol is placed. The weld size, length, and other specifications should be indicated next to or below the FP symbol on the welding symbol to provide further guidance to the welder. It is important to follow the welding symbol precisely to ensure the weld meets the required specifications and standards.
To test an ultrasonic weld, you can perform non-destructive tests like visual inspection for any visible defects, ultrasonic testing to check for bond integrity, and pull or shear testing to measure the strength of the weld. These tests help ensure the quality and reliability of the weld.
