tell me full penetration joint process
There are several types of welds, including butt welds, where two pieces are joined end-to-end; lap welds, where one piece overlaps the other; corner welds, used to join two pieces at a right angle; and T-welds, which connect two pieces at a T-shape. Other types include edge welds and plug welds. Each type serves specific applications based on the joint configuration and structural requirements.
If its small insert piece, it should be 300 mm as IACS standard.
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.

Whenever 2 pcs. of metal come together at an angle to each other. Butt welds are 2 pcs of metal that meet edge to edge.
Back welds and backing welds serve different purposes in welding. A back weld is a weld applied to the reverse side of a joint, typically to reinforce it or ensure complete fusion, while a backing weld is a type of weld made on a backing bar or plate that supports the root of the weld joint, helping to prevent defects and provide a solid foundation. Essentially, back welds reinforce the joint, whereas backing welds provide support during the welding process.

The plural of 'weld' is 'welds', as in "He made several welds to the car frame."
Short welds made to hold a joint in proper alignment are called "tack welds." These temporary welds provide stability during the assembly process, ensuring that parts remain positioned correctly before the final welds are applied. Tack welds are typically small and used primarily to secure components in place for further welding operations.
If its small insert piece, it should be 300 mm as IACS standard.
it's a mixture between what is called " beed welds"
it welds
The force caused by tiny collisions and micro welds that hold surfaces together is called adhesion force. It is the attraction between molecules on different surfaces that causes them to stick together.
