Tack welding is short weld runs given when a work piece is assembled in strategic places. It help to combat pull in the metal associated with full welding runs. It also help in assembly and to rework material if mistakes in meterial measurements have been made as it is easy to break the tackweld of and start over

What is buttering process in metal fabrication?
Buttering: the addition of material, by welding, on one or both faces of a joint, prior to the preparation of the joint for final welding, for the purpose of providing a suitable transition weld deposit for the subsequent completion of the joint. Simply it is weld build up of (one or both) base metal(s) before beginning to weld the joint itself. This can be done in order to make up for poor joint preparation as indicated previously, but also is done to minimize the effect of PWHT on a sensitive material or eliminate subsequent PWHT.
How do you do zinc welding?
Zinc welding is typically done using gas metal arc welding (GMAW) or flux-cored arc welding (FCAW) processes. It's important to use proper ventilation and personal protective equipment when welding zinc to avoid exposure to harmful fumes. Additionally, cleaning the zinc surface before welding and selecting the appropriate filler material are essential for achieving a strong weld.
What must be done to prevent porosity in welding?
what must be done to prevent this from happening
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).
Where do you prefer arc welding?
Almost all welding today is done with electricity (Arc Welding) even on cast iron. SMAW, GTAW, GMAW etc. --AW means Arc Welding.
How argon welding done?
Argon welding, also known as TIG (tungsten inert gas) welding, involves using a non-consumable tungsten electrode to create an electric arc that heats the metal workpieces. Argon gas is used as a shielding gas to protect the weld area from atmospheric contamination. The welder manually feeds filler material into the weld joint as needed to create a strong and clean weld.
What is a bad solder joint?
A soldered joint that was done poorly.
Would a complete knee replacement be preexisting condition?
Yes. In order to have a knee replacement done you must first have a significant amount of damage to the knee joint. That is your preexisting condition. The knee replacement itself was done to replace the damaged joint and may or may not be considered a preexisting condition.
The majority of SMAW welding is done using what two polarities?
