Can gi pipe weld with ms?
Very likely to leak, zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.
How do you compute the pipe length?
minus weld gaps and takeoffs from total then multiply for angle.
What type of joints can be used for GI pipes?
Threading joint, weld joint, Flanges joint
How does arc length affect a weld?
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.
How do you weld MS pipe to GI pipe?
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.
What is weld mapping?
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.
Can you make a four door nova into a two door?
you could weld up the back doors but it will still not look like a 2 door.
What is a weld map look like?
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.
Why work to a recognised standard when producing engineering drawings?
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".
What is tackweld?
like a spot weld, you don't weld 100 percent until it's all together and everything is square
Can you weld cast aluminum?
Yes..look up alumaloy welding rods
What welding parameters to consider to produce quality weld?
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.
What do you mean by seam welding where it is used?
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
Is ther a diagram to now how many weld inches is in a 20 weld -.344 WT grad x60?
Pick up a rock and look under erneath it and maybe you find the answer
What are structural draftsman?
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.
How close can one weld be to another weld?
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
Who is Theodore Weld?
