when length of reinforcing bar is small and we have to provide longer reinforcement in that case the second bar is provided with proper overlapping with the first bar this overlapping is known as lap length.
the straight length of shall not be less than 12mm dia and 200mm length.

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.
Why not weld on concrete?
Welding on concrete is not advisable because the high temperatures involved can cause thermal shock, leading to cracking and damage to the concrete. Additionally, the sparks and molten metal produced during welding can create fire hazards and damage the surface. It's also challenging to maintain a stable and level work surface on concrete, which can compromise the quality of the weld. Instead, it's better to use metal surfaces or designated welding tables.
What are five things the welding symbol will tell the welder about the weld that is to be made?
The welding symbol provides essential information about the weld, including the type of weld (e.g., fillet, groove), the size of the weld, the length of the weld, the welding process to be used, and any specific requirements for the weld, such as the finish or pre-weld treatments. It may also indicate the position of the weld and any additional details regarding the joint preparation. This standardized communication ensures consistency and clarity in welding operations.
How many inches of weld on pipe?
The amount of weld on a pipe can vary significantly based on the application, pipe diameter, and welding process used. Typically, the weld length is determined by the joint design and the specifications of the project. For example, a full penetration butt weld may require a continuous weld along the joint, while a fillet weld may only need to cover a portion of the joint. Always refer to project specifications or standards for precise requirements.

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.

How do you calculate the number of welding rods needed for a fillet weld?
To calculate the number of welding rods needed for a fillet weld, first determine the weld size and length required. Use the formula for the volume of the weld, which is the weld size (throat thickness) multiplied by the length of the weld and the number of passes needed. Then, convert this volume into weight by considering the density of the welding rod material. Finally, divide the total weight of the weld metal by the weight of a single welding rod to find the number of rods required.
What is tack weld length?
Tack weld length refers to the short, temporary welds made to hold two pieces of material in place before the final welding process. These welds are typically made to ensure proper alignment and stability of the components during fabrication. The length of a tack weld can vary based on the materials being welded and the specific requirements of the project, but it is generally shorter than a full weld. Properly sized tack welds help prevent distortion and ensure a strong final weld.
How do you build a reinforced concrete slab?

How can the integrity of an oxidized weld be restored to ensure its strength and durability?
To restore the integrity of an oxidized weld and ensure its strength and durability, the weld can be cleaned and polished to remove the oxidation. This can be done using methods such as grinding, sanding, or chemical cleaning. Once the oxidation is removed, the weld can be re-welded or reinforced as needed to strengthen it and ensure its durability. Regular maintenance and inspection can also help prevent future oxidation and maintain the integrity of the weld.
How do you measure weld throat thickness?
Weld throat thickness is measured from the root of the weld to the face of the weld, specifically the shortest distance in a cross-section of the weld. This measurement is crucial for ensuring the weld meets design specifications and can be done using calipers or a weld gauge. For fillet welds, the throat thickness can also be calculated using the formula: throat thickness = 0.707 times the leg length of the weld. Accurate measurement is essential for assessing the strength and quality of the weld.
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.
