Here we are going to see about two types of weld Joints
Groove Welds
Fillet Welds Dimensions
1.1. Groove Welds:
In the following figures, the perspective drawings of types of weld joints are shown at the left, looking at each joint from the arrow side. The…
Welding Inspection duties
General Conditions:
Understand shop drawings, erection drawings, referenced codes and standards. Review the manufacturer’s Material Test Report (MTR). Verify all materials properties and that all materials are readily identifiable and traceable to an MTR.
Conduct a complete visual examination…
Equipment’s required for Welding Institute set up.
Welding is a process of joining metals or nonmetals such as plastic.
There are different types of welding, and few of them are as below.
SMAW- Shielded Metal Arc Welding (commonly…
Welding Safety with Gas Cylinders
On an oxyacetylene system there will be three types of valves, the cylinder valve, the regulator valve, and the torch valve. There will always be a set of three valves for each system, since the gas in the cylinders is…
As in any welding process, safety precautions are very important. All information relating to the safe operation of the welding equipment and process must be fully understood before beginning work.
A careless welder who does not observe some simple rules can cause a dangerous situation…
Weld crack
1.1. Cracking:
If a weld crack is found, it must be removed and magnetic-particle inspection performed to ensure every point has been removed before re-welding. Weld Crack can occur on top of a weld…
Why use this TIG welding process:
TIG Tungsten Inert Gas otherwise called as GTAW- Gas Tungsten Arc Welding , Involves melting the metal using the arc created by tungsten electrode,
The welding can be done with or without filler metal,
Argon Gas is used as shielding around…
WELDING FOR JOISTS AND FINISHING OF MACHINING RAILS
Unless otherwise authorized by the engineer, any welding to the top flange of steel members for supporting floor form joists and finishing machine rails will not be permitted. Welding of hangers and supports to shear studs will…
Bend Test Coupon Preparation
First the centerline on the plate shall be marked. Then another line 1.0 inch above the center line and another line 1 inch below the center line.
This is the section that can be used as an alternate coupon in the event…
Welding Procedures
Follow a clear example of test coupons welding procedures for a 3G welding certification. In this 3G welding procedure the notes were taken from the same section of the AWS code that are used for the 3/8 inch limited thickness test procedure.
