What are the important factors in making a weld?
The most important factors include the size and type of weld, edge preparation, metal thickness, reinforcement members and distortion. Each of the above factors can affect and change the process of welding.
What are the four modes of GMAW metal transfer?
There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations.

What are the factors affecting welding cost?
The most important factors in determining the welding cost are labor requirements, overhead allocations, and materials.
What are the welding parameters that must be considered to produce quality weld?
What welding parameters must be considered to produce a quality weld? The top welding parameters to take into consideration when welding are amperage, voltage and wire feed speed. All of these can affect the finished weld if these welding parameters are not properly set.
What four factors must an arc welder control in order to produce an acceptable bead?
The movement or weaving of the welding electrode can control the following characteristics of the weld bead: penetration, buildup, width, porosity, undercut, overlap, and slag inclusions.
What factors affect the weld quality of Weld in fabricated products?
Following factors affects the weld quality of weld in fabricated products made by arc and gas welding 2. incorrect dimensions. 3. Incorrect shape of weld 5. Less corrosion resistance.
How do I determine the appropriate welding process?
To determine the appropriate welding process, keep your efforts focused on the requirements of the weld joint. A joint that requires, or can be welded by, just one arc welding process is rare. In fact, the majority of joints usually are characterized by a combination of these requirements to varying degrees.
What is the importance of welding on ships?
Welding is one of the most critical operations within ship construction. When welds fail, often the whole structure fails. A good quality of weld can satisfy the need of insurance companies they demands that the weld should fulfill following requirements as regards the weld quality.
What determines the strength quality of a weld joint?
The strength quality of a weld joint has a close relationship with joint efficiency determined by the strength of the materials as well as with the welding process. For example, a butt joint of structural steel increases the strength of the weld metal and heat-affected zone to be higher than the strength of the base materials.
