What effect on the weld cost does increasing the groove angle have?

After studying the Indian Welding Journal published by Indian Welding Society it is observed that distortion and residual stresses increase with increase in groove angle . Joints strength also increases with groove angle increase of the welded material which affects the economy of welding.

What is groove angle in welding?

The included angle between the groove faces of a weld groove.

What is the most important factor in a groove weld?

The most important factors include the size and type of weld, edge preparation, metal thickness, reinforcement members and distortion. Each of the above factors can affect and change the process of welding.

What determines the size of a groove weld?

The size of weld will be shown to the left of the groove symbol in parenthesis. If there is no number in parenthesis then the size of the weld should not be less than the groove depth. Welding symbol showing both groove depth and weld size. 7.

How does the bevel angle in a groove weld affect the filler metal volume?

For groove welds the bevel angle greatly affects the filler metal volume. As the groove angle increases, a larger volume of filler metal is required to fill it during welding.

What is single bevel groove weld?

[′siŋ·gəl ¦bev·əl ′grüv ‚weld] (metallurgy) A groove weld in which one member has a joint edge beveled from one side.

What is included angle in welding?

Bevel angle is the angle at which a single plate is prepared, while included angle is the total angle formed by the preparation of both plates. For a single-bevel groove weld, the bevel angle is equal to the included angle, but for a single-v groove weld, this is not the case.

What are factors affecting temperature in welding arc?

The major factors are (1) the solidification rate of weld metal (2) the distribution of maximum temperature in weld heat affected zone (3) the cooling rate in weld metal and HAZ (4) the distribution of heat in weldmetal and HAZ[6].

How do you determine weld length how weld size will be decided?

The size of a fillet weld should be calculated by the designer of the welded structure, based on the nature and magnitude of applied loads, on the material and on the design basis.

What is a single bevel groove weld?

What is the minimum size of a root pass in welding?

The minimum size of a root pass shall be sufficient to prevent cracking but not less than 1/8”. The maximum thickness of root passes in groove welds shall be ¼ in. The maximum size of single-pass fillet welds and root beads of multiple-pass fillet welds shall be: 3/8 in. for the flat (1F) position

What is the maximum thickness of a fillet weld?

The maximum thickness of root passes in groove welds shall be ¼ in. The maximum size of single-pass fillet welds and root beads of multiple-pass fillet welds shall be: 3/8 in. for the flat (1F) position 5/16 in. for the horizontal (2F) and overhead (4F) positions

What is the minimum gap between lap joint and butt weld?

The gap between faying surfaces of lap joints or butt welds utilizing backing shall not exceed 1/16 in.

What are the requirements for the purchase of welding filler material?

Requirements for the purchase and control of welding filler material shall be in accordance with GWS 1-03, Welding and Brazing Material Procurement and Control. Welding filler materials (electrodes, bare filler wire, etc.) must be utilized by welders making weldments with this procedure. Welders shall not perform welds autogenously.
