One should never cut or weld directly against?
You should not weld on concrete, as it can explode if heated
How do you calculate weld deposit metal weight?
At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.
How do you measure filet weld?
In a fillet weld, the leg and size are the same for the convex weld.
How would you avoid the occurrence of porosity or slag on weld?

What is the difference between butt weld and socket weld?
A butt weld is a weld made between two straight cut profiles , a socket , or plug weld is made between a surface and a hole.

Best 550d tmt bars for construction?
Agni Steels' TMT bars undergo a comprehensive TMT treatment. In this process, the steel TMT bars receive a short, intensive cooling as they pass through the specially designed water cooling system after the last Rolling Mill Stand. Our steel bars are processed to bond better with concrete cement mixtures and maintain high strength while remaining convenient to bend and weld.

At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.
How do you build a reinforced concrete slab?
by using blueprints to a perfection. the right number of mats, size of rebar, the right spacing for bond beams, the right number of ties or cad-weld as per code as well as inspection. making all your tie-ins to code and due not miss any revisions or details.
What mechanical properties of a weld in carbon manganese steel is most affected if the heat input per unit length of weld is excessively high?
Toughness
What is the required length for common weld bar joints?
Absorbs water and nutrients:))
How does arc length affect a weld?
Too long an arc length allows the arc to wander creating a poorly shaped weld. The slag is usually too thin and can allow Oxygen in the air to attack the molten puddle which causes Porosity in the weld. Too short an arc length buries the slag and creates less heat which traps the slag and impurities. Keep in mind that electrode coatings help determine the correct arc length.
Is there required size for a seal weld per AISC?
The required size for a seal weld per AISC is eighteen foot length. AISC also specifies minimum weld size based on the thicknesses of the members joined.
How do you compute the pipe length?
minus weld gaps and takeoffs from total then multiply for angle.
Does soldner glaze or jb weld works on alunium baking sheet need to cut length and put end back together?
Solder glaze or JB Weld will not work on aluminum baking sheet. These bonding materials are used only for the surfaces of metal, wood, fiberglass, PVC, ABS, concrete, glass and fabric. This material should avoid clean slick or oily surfaces.
