Is welding allowed in reinforcement?
Yes we can weld bars instead of lapping but it is not recommended in huge quantity.
Why welding is not allowed in reinforcement?
Many people avoid welding rebar because the concrete and the rebar in the final piece will expand and contract at different rates, so having the rebar welded together creates pressure points where the concrete can crack.
Is welding allowed in TMT bars?
Welding can be allowed if the metallurgical piece of the weld metal is with the end goal that the proportional carbon content is under 0.4 \%. There are different welding forms for joining the materials.
Is code for welding of reinforcement bars?
IS 2751: Code of Practice for Welding of Mild Steel Plain and Deformed Bars for Reinforced Concrete Construction.
What is reinforcement in welding?
[‚rē·ən′fȯrs·mənt əv ′weld] (metallurgy) Weld metal that extends beyond the surface or plane of the weld joint.

What is the difference between A615 and A706 rebar?
Conventional reinforcing steel is used in the majority of reinforced concrete structures. Results from this study indicate that ASTM A706 reinforcing steel exhibits lower critical chloride threshold levels and higher corrosion rates than ASTM A615 reinforcing steel when embedded in cementitious materials.
What is reinforcement in weld?
What is weld reinforcement?
Weld metal in excess of the quantity required to fill a joint.
Is standard for welding electrode?
The electrodes are generally manufactured in the length of 250mm to 450mm. The Indian Railways has issued standard specification IRSM 28-2012 for manual metal arc welding electrodes and gas welding rods.
What is height of reinforcement in welding?
The weld height reinforcement is the maximum distance between the base metal level and the top point of the deposited metal. This gives an idea of the number of filling passes that are required to fill the gap and the convexity has a direct correlation with the strength of welded joint and welding wire consumption.
Is it acceptable to drill through a reinforced concrete column?
If by “drilling through” you mean drilling a hole that is as deep as the reinforced concrete beam or column itself, then it is not acceptable. It should not be attempted even if it is a very small diameter hole.
Can you drill through a reinforced concrete beam to attach pipes?
Generally speaking the screws to attach pipes are small (5–6mm or 1/4″) and they are not deep (20–30mm or 1″). As the screws are not going too deep into the member, It depends. If by “drilling through” you mean drilling a hole that is as deep as the reinforced concrete beam or column itself, then it is not acceptable.
What happens if there is too much reinforcement in a beam?
The amount of steel reinforcement is limited. Too much reinforcement, or over-reinforced will not allow the steel to yield before the concrete crushes and there is a sudden failure. A beam with the proper amount of steel to allow it to yield at failure is said to be under reinforced.
How much space do you need for a concrete beam?
For indoor exposure, 3/4 inch is required for slabs, 1.5 inch is typical for beams, and for concrete cast against soil, 3 inches is typical. Minimum bar spacings are specified to allow proper consolidation of concrete around the reinforcement.
