Welding Position is the essential part of welding that is the basis of any welding process. 1G welding position is the most common one used for welding: it is the flat vertical welding position where the welding electrode is held in the vertical position and the metal is held in a flat horizontal position. In fact, in the aluminum and steel industries, 1G welding position accounts for 80% of the total welding.
It involves fewer passes, less reshaping of the metal, and can be used for both simple and complex shapes. Therefore, 1G welding position is an important welding technique that requires highly skilled welders.
In this article, we will discuss in detail about 1G welding position and its importance in the welding industry.
What is 1G Welding Position?Welding is a process that joins two metals together by heating either metal and depositing a third metal to fill the joint between them. In welding, the position of the weld is determined by the angle of the welding arc.
The welding positions are numbered from 1 to 6 and describe the orientation of the weld in relation to the two base metals. The most commonly used position is the 1G welding position.
Definition:The 1G welding position is defined as welding in the flat or horizontal position. It involves the welding of two bases or sheets of metal in a flat position. In this position, the weld joint is on top of the metal base and the arc is applied from the top downward.
The metal base is held in position by welding equipment and the welding heat is applied from the top of the metal base.
Advantages of 1G Welding Position:
- The 1G welding position is relatively easy to learn and can be mastered by most welders within a short amount of time.
- It requires minimal set-up and requires little manipulation of the welding equipment.
- There is no distortion of the metal due to the welding process.
- The weld zone has a flat surface and good access to the weld zone.
- The deposited weld metal is of high quality due to good contact between the weld metal and base metal.
Disadvantages of 1G Welding Position:
- The 1G welding position is limited to welding in only the flat or horizontal position.
- Welding in the 1G welding position can be tiring and repetitive, as the welder needs to maintain the same position throughout the weld job.
- The weld pattern is difficult to evaluate due to the flat surface making it impossible to follow the weld line visually.
- Welding in the 1G welding position can be difficult for welders with limited experience or those who are not comfortable working in tight spaces.
