What is the difference between 5g and 6g welding

Welders can perform these two welds in all four positions. Besides this, there are special letters to designate fillet and groove welds. Fillet Weld F — It is a welding method for combining two parts of metal vertically or slightly at an angle. Groove Weld G — It is a weld made in the groove.

It requires full penetration for laying strong welds. Normally there are six welding positions with certain numbers and letter i. All the positions are used in various angles and shapes while performing welding. Generally, the ways and ideas of welding are similar in different countries. But the AWS D1. In this weld position, welders put metal piece right below the torch. This position is performed for butt, groove and fillet welds as well. This is a horizontal position for butt welds.

It is harder than the 1F position. But the exact angle of torch depends on the angles of the plate and pipe. This happens due to the molted metal flowing downward of the joint and the torch heat rises upward of the joint.

Consequently, a uniform deposit cannot be applied to joints. The skill of the welder is evaluated by welder performance qualification. So, things like position, backing, uphill, and downhill, etc. The welder conducts welding from the top of the pipe. Welder position does not change.

The welder conducts welding from the side of the pipe with horizontal welding direction. Welder conducts welding while moving around the pipe. This position is almost the same as the 1G position, only the pipe cannot be rotated. In 5G, welding is done vertically either upwards or downwards. This pipe welding position is the most difficult welding position.

Only the welder has enough experience capable of welding with a 6G position. Pipe in a sloping position which is around 45 degrees from the horizontal axis X-axis or 45 degrees from the vertical axis Y-axis. The horizontal or 2G position is a bit more complicated than the flat position. As with vertical and overhead, horizontal positions can be more challenging to perform and require a higher level of skill.

In this position, the workpiece is held parallel to your body while welding. In this way, the workpiece remains in front of you while welding. This position can be used to obtain either a fillet or a groove weld. For a fillet weld, the torch will be held at a degree angle. The weld axis is horizontal. How the positions are executed depends on the type of weld.

For fillet welds, the weld bead is placed where a vertical and horizontal piece of metal meet at a degree angle. When welding a groove, the weld face will be along a vertical plane.

One of the major problems when performing these welds is the molten metal flowing down and accumulating. Welding in a vertical position downhill or uphill can prevent this problem. In this position, both the weld and the workpiece are located vertically. One problem with this is the tendency of the molten metal to flow downward and upward due to gravity. To remedy this, torches have to be kept at an angle of 45 degrees.

In addition, you use the lower metal of the workpiece to achieve a vertical climbing position. Like the vertical uphill positions, the workpiece is also placed in the vertical downhill position in a vertical position.

However, instead of using the lower metal of the workpiece, you use the upper part of the workpiece. The overhead positions are the most difficult position for weld work. Welding will be done with two pieces of metal on top of the welder, and the welder will have to angle himself and the equipment to reach the joints. A major issue may be the loosening of metal from the plate. What is G Welding? What does the G stand for in 3G welding? What is the difference between 5G and 6G Welding?
