It's "ultrasonic weld," rather than "sound weld." Sounds more "engineering-ish," anyway.
This is done by clamping two objects together - usually plastic ones, but thin metal can also be ultrasonically welded - and directing a high-power beam of ultrasonic energy at the mating point. The beam causes heat, which makes the two materials in the joint melt. When they cool down, they're fused together.
Welded is the joining of two pieces of metal where the parent metal is heated to it's melting point. Filler metal, if any, is the same composition as the pieces to be joined. This is in contrast to brazing or soldering, where the pieces to be joined do not reach the melting point, and the filler metal is of different composition, with a lower melting point.
Pipes that have been welded (or melted) together.
no, welded wires are not powerful, it can be used only where the area of slab is small.
coil welded type
Better in what way? Rivited joints are generally cheaper while welded joints are generally stronger.
High Frequency Welded Pipe
Do you mean welded wire fabric?
It is called aluminum welding. Aluminum can be TIG welded, the most common method, or oxy-fuel welded, or stick welded, or MIG welded.
What have you welded ?

Pipes that have been welded (or melted) together.
Double submerged arc welded pipes has two types, one is spiral welded pipes, and the other is longitudinal welded pipes which are different from EFW pipes.
welded on
Cut it off, it is welded on.Cut it off, it is welded on.
Its welded.
I have an 87 Ranger and it is welded on.
If it can be welded it can probably be TIG welded. Exceptions would be metals with a low melting temperature ie: lead, tin, zinc etc.
The past tense of weld is welded.
