It is a layer of weld applied to base metal like butter on bread. Commonly used to join dissimilar metals that are not compatible to each other. Once the area is buttered a weld can be made using material that is compatible to the base metal and the butter. Or a layer of metal that protects the base metal from exposure to another element. Typical application might be a valve to be installed where only one area is exposed to an element that might corrode/destroy it such as salt water. It is used a lot on ships where making the whole part would be too expensive. Fabricate the item from steel, then butter the area/s that will be exposed to salt water with stainless steel. It can also be used where extra hardness or wear resistance is required such as cutting edges, plow blades, snow plow pads etc.

What is difference between seam welding and spot welding?
The only difference between the two is that projection welding requires preparation of the joint members in the way of adding a preformed dimple or projection. Spot welding is used without such preparation to the joint members. it's just heat and pressure.
How to avoid surface concavity in autogeneous welding?
Do you mean your beads are concave and you would like them convex in appearance while autogenous welding is being done? Without knowing what metal you are welding or seeing the technique used I can only offer generalizations. It could be a lack of sufficient sulfur or improper travel speed. Without more info I'm only guessing.Which isn't good when it comes to welding.
What is back step welding?
Backstep welding is a technique to avoid distortion while welding on thin sheets. In the backstep technique, the general progression of welding may be left to right, but each bead segment is deposited from right to left. As each bead segment is placed, the heated edges expand, which temporarily separates the plates at B. As the heat moves out across the plate to C, expansion along outer edges CD brings the plates back together. This separation is most pronounced as the first bead. With successive beads, the plates expand less and less because of the restraint from the prior welds.
What is the welding cert roster code for welding?
roster welding
Name of the type of welding?
One type of welding is tube welding. Another type if mig welding.
What is step back welding and why this technique applied?
step by step stich welding
When was Been Caught Buttering created?
Been Caught Buttering was created in 1991.
What is buttering process in metal fabrication?
Buttering is the process of applying a layer of weld metal to a base material before performing the final weld. It helps to improve the bond between the base metal and the final weld metal, ensuring better strength, corrosion resistance, and overall quality of the weld joint. Buttering is commonly used in metal fabrication to prevent issues like cracking and to ensure a more uniform weld.
Name and explain the two methods of striking an arc in arc welding?
There is two technique of arc initiation, first TAPPING Technique and second SCRATCH Technique. TAPING Technique is generally use in GTAW and SCRATCH Technique is used for SMAW process.
Is buttering toast a physical or chemical change?
Physical change.
What is the back step welding and why is this technique applied?
This technique involves a continual stalling of the forward travel motion by traveling backwards slightly, into the previous deposited weld. This technique has two particular functions; it helps improve the final microstructure, by reducing the solidification rate of the weld puddle and increases throat thickness.
