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 is the welding method and welding rods for weld EN 24 steel?
d2
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 do you mean by seam welding where it is used?
seam welding is a process that produces a weld at the faying surfaces of two similar metals where its used depends on which metal you look to weld
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 is a 1g weld?
flat
What are welding?
1g,2g,5g and 6g in pipe welding
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.
What causes warpage or distortion during welding?
Warping in welding is caused by shrinkage of weld metal, faulty clamping of parts, faulty preparation and overheating of joints. Distortion in welding is caused by uneven heating, improper sequence and the shrinkage of the deposited metal.
What does a welding instructor do?
Teach you how to weld
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 the welding method and welding rods for weld EN 24 steel?
d2
What is the difference between shielded and unshielded welding?
Shielded welding needs a gas to shield the weld from the atmoshere air. Unshielded uses a flux the burns when welding to shield the weld from the atmoshere air.
Can metallic bonds be formed from a welded joint?
Yes, welding of metals typically involves heating and fusion in resistance welding, arc welding, acetylene torch welding. Metallic bonds are formed between the substrate and the weld. The composition of the weld and the substrate around the weld inevitably is different from the material being welded.
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.
What is the function of slag for welding?
The slag in the welding process protects the weld from oxidation and slows down the rate at which the weld cools. It also prevents brittleness of the metal.
