An alignment weld is a type of weld used to ensure that two components are properly aligned before final welding operations. It typically involves making a short weld between the parts to hold them in place and maintain their desired position during subsequent welding processes. This technique helps prevent distortion and ensures the structural integrity of the assembly. Alignment welds are often used in fabrication and assembly of various metal structures.
Butt weld and groove weld are two common types of weld joints used in welding processes. A butt weld is a type of weld where two pieces of metal are joined together along their edges in a single plane, creating a smooth, flush surface. On the other hand, a groove weld is a type of weld where a groove or channel is created in one or both of the pieces being joined, and the filler material is deposited into the groove to create the weld. Both types of weld joints are used in various applications depending on the specific requirements of the project.
It is one way to "Stress Relieve" the weld joint. As the weld metal metal cools it contracts and hammering on the weld expands it. On thick sections it is done after every layer of weld. Often used when welding cast iron or other metals with a low COE (Coefficient of Expansion).
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.

The "toes of a weld" refer to the edges where the weld metal meets the base material. This area is critical for assessing the quality and integrity of the weld, as defects or discontinuities at the toes can lead to weaknesses in the joint. Proper fusion and alignment at the toes are essential for ensuring the strength and durability of the welded connection. Inspecting the toes helps ensure that the weld meets specified standards and performance criteria.
The first weld made when joining two pipes with beveled edges is called the "root pass." This initial weld establishes a foundational joint at the root of the bevel, ensuring proper penetration and alignment of the joint before subsequent layers or passes are added. It is crucial for the strength and integrity of the overall weld.
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.
To check welded joints for uniformity, alignment, position, weld size, and profile, you can conduct visual inspections to identify any surface irregularities or misalignments. Use measuring tools like calipers or gauges to assess weld size and ensure it meets specified standards. Non-destructive testing methods, such as ultrasonic testing or radiographic inspection, can also be employed to evaluate internal integrity and uniformity. Finally, documentation of the inspection results helps ensure compliance with relevant standards and specifications.
Not incorporating a gap in a butt weld pipe can lead to several dangers, including the risk of excessive stress concentration at the weld joint, which may result in cracking or failure under pressure. Additionally, lack of a gap can hinder proper penetration of the weld, compromising the joint's integrity and increasing the likelihood of leaks. It may also cause distortion or warping during the welding process, affecting the alignment and overall performance of the piping system.
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.
To check welded joints for uniformity, alignment, position, weld size, and profile, you can use visual inspection and measurement tools. Start by examining the joint visually for consistent bead appearance and any signs of defects like cracks or porosity. Use calipers or gauges to measure the weld size and ensure it meets specified standards, checking the profile for proper contour. Additionally, alignment can be assessed by verifying that the components are properly positioned and aligned according to the design specifications, often using straightedges or laser alignment tools.

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.
WELD - AM - was created in 1956.
