What else can I help you with?
What is positional welding?
A welding position is the orientation of the weld joint, whether that be flat, horizontal, vertical, or overhead.
What is 4g welding?
4G is a welding position. The '4' means the weld is to be made in the overhead position. The 'G' means the weld is a groove weld.
In Gas tungsten arc welding what is the gas pressure in overhead position welding is it higher or lower then flat and vertical i.e. 15-25CFH?
lower
What is used in welding?
A device that can generate heat. Melted material and the welding operation is performed.
What is 4G in welding?
1G is flat 2G is horizontal 3G is vertical 4G is overhead 5G is pipe
What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
What is over head position welding?
When the weld is made from under the joint.
What welding position has the highest heat input?
Heat rises so in my experience it is always overhead that has the most heat input.
Why is it essential to use a lower current and a shorter arc length when welding in a horizontal position?
Flat, Horiz. and Overhead welding normally take the same amount of Amperage. The electrode angle would change.
When performing overhead welding what additional safety equipment should be worn in order to protect the legs and feet from falling molten metal?
When welding one should always wear certain clothing. Leather boots (steel toe desirable), work pants (such as jeans) that cover the top of the boots, heavy cotton long sleeve shirt, welding beanie, gloves, and safety glasses. In most instances these items will protect you from sparks and weld spatter whether you are welding on a flat, vertical or overhead surface. A leather jacket can be worn to protect your shoulders and arms. Molten metal should not be falling if you are welding correctly. If you are sitting, while welding, a leather apron should be used.
What type of company would perform tig welding jobs?
Usually tig welding is performed by a company specialized in manufacturing parts for automobiles or electronics. It also can be performed by a wide variety of companies to fix or prepare machines or parts.
Should braze welding be done in flat position?
Flat position welding is when your job is in a horizontal position the easiest and best position to do welding, then you get vertical up position where the trick is to weave your arc in a V formation, vertical down is used on thin material if its possible at an angle of 45 degrees last overhead that is the most difficult the opposite of flat welding where the job is upside down anytime you look directly down on your weld joint, it is a flat weld, flat position weld are not affected by gravity, as opposed to horizontal, vertical, and overhead, all of which the puddle tends to "sag" as you weld
