There are many different factors that may determine welding sequence. Of course, a 1G weld is defined as a Flat (1) Groove (G) weld and the 1G is usually used when describing the position of welding any flat material such as bar, sheet, or plate. The thickness of the material may affect sequence.

For 3/16" (some may say 1/4") thick material, one pass is utilized to fill the joint. Most codes will limit per pass thicknesses to 1/4" thick depending on the process used, but when welding 1/4" thick material the likliness of incomplete penetration, incomplete fusion, or excessive undercut at the toes of the face side of the joint are very high, which results in most 1/4" material to be welded using 2 passes (multipass).

Another factor may be the end result of the material being welding, such as minimal distortion which is a result of heat input. Weaving will reduce the number of welds that are needed but will result in longer 'on time' of the heat input and will increase the amount of heat input to the base metal. A good, fool proof way of welding a flat groove weld is to always work from back to front (when multipass welding) which always allows for proper tie in or penetration of the weld metal either into the base metal or to each prior pass.

What is it welding sequence and explain about it?

Weld sequence would specify the order in which welds are to be made on a structure to help against distortion and residual stresses.


What are five things the welding symbol will tell the welder about the weld that is to be made?

The welding symbol provides essential information about the weld, including the type of weld (e.g., fillet, groove), the size of the weld, the length of the weld, the welding process to be used, and any specific requirements for the weld, such as the finish or pre-weld treatments. It may also indicate the position of the weld and any additional details regarding the joint preparation. This standardized communication ensures consistency and clarity in welding operations.

What is a fusion weld?

A fusion weld has no filler material. The pieces to be joined are touching and heat is applied at the joint. The edges melt and "fuse/weld" together. TIG or Oxy-fuel Welding is used. This type of welding is considered to be pure as nothing is added to the weld.


What is meant by the term welding and draw various welding symbols?

Welding is the process of joining two metals, usually involving a heat source. Welding symbols are the symbols used on part prints or assembly drawings to show size and type of weld, the specific welding process, and many other variables pertaining to that particular weld. A welding symbol looks like an arrow pointing to the location of the weld, with a horizontal line 'carrying' other symbols and numbers that describe how to make that weld. A picture of a welding symbol can be found when an image search is done.

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.

Why the slag come in welding?

Slag in welding is formed when the flux coating on the welding electrode melts and lays over the weld pool. It helps protect the weld from atmospheric contamination, acts as a coolant, and facilitates the removal of impurities from the weld. After the weld cools, the slag can be easily removed.


How close can one weld be to another weld?

Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.


What is weld spatter?

Weld spatter refers to the small bits of molten metal that can be expelled from the welding process. It can occur when excess welding wire or flux is present, leading to weld spatter landing on the workpiece or surrounding areas. Weld spatter can cause damage to the welding equipment, affect the quality of the weld, and create safety hazards.

What is the function of slag for welding?

Slag in welding acts as a protective layer on the molten weld pool. It helps to prevent contamination from the atmosphere, improve the weld's appearance, and facilitate the solidification process of the weld metal.


How do you calculate the number of welding rods needed for a fillet weld?

To calculate the number of welding rods needed for a fillet weld, first determine the weld size and length required. Use the formula for the volume of the weld, which is the weld size (throat thickness) multiplied by the length of the weld and the number of passes needed. Then, convert this volume into weight by considering the density of the welding rod material. Finally, divide the total weight of the weld metal by the weight of a single welding rod to find the number of rods required.


How much are classes for welding?

Classes for welding are to help you learn how to weld and how not to burn yourself. They have books on how to weld and everything to do with it.
