M.I.G.
and M.A.G.S.
Advantages
1) Higher welding speeds
2) Greater deposition rates
3) Less post welding cleaning (e.g.
no slag to chip off weld)
4) Better weld pool visibility
5) No stub end losses or wasted man hours caused by changing electrodes
6) Low skill factor required to operate M.I.G
/ M.A.G.S
welding torch
7) Positional welding offers no problems when compared to other processes. (Use dip or pulsed mode of transfer)
8) The process is easily automated
9) No fluxes required in most cases
10) Ultra low hydrogen process
M.I.G.
and M.A.G.S.
Disadvantages
1) Higher initial setup cost
2) Atmosphere surrounding the welding process has to be stable (hence the shielding gasses), therefore this process is limited to draught free conditions
3) Higher maintenance costs due to extra electronic components
4) The setting of plant variables requires a high skill level
5) Less efficient where high duty cycle requirements are necessary
6) Radiation effects are more severe
Mechanical joints can be categorized into various types, including bolted, welded, and riveted joints, each with its advantages and disadvantages. Bolted joints are easy to assemble and disassemble, making repairs straightforward, but they may require additional components like washers and can introduce stress concentrations. Welded joints provide high strength and are often more compact, but they can be difficult to inspect and repair, and may require specialized skills. Riveted joints are durable and can accommodate some movement, but they are generally heavier and less versatile than bolts or welds.
leak free joints are provided
Better in what way? Rivited joints are generally cheaper while welded joints are generally stronger.

advantages of a dowels joint is they don't need nails and they are more secure than just using glue also they are strong. disadvantages are drilling accurate holes can be difficult

The different types of joints in steel structures include welded joints, bolted joints, and riveted joints. Welded joints involve fusing steel members together using heat, while bolted joints use bolts to hold steel members together. Riveted joints use rivets to connect steel members through a hole punched in both pieces.
