Advantages Disadvantages

It is inexpensive. Any traces of

carbon left in theweld will weaken it.

Requires very littlespecialized

equipment.

If flame distance isnot proper it can

burn through the

metal instead of

welding it.

Advantages Disadvantages

Process is

Automated.

Cannot be used for

joining two metals.Only used for

cladding.

Since a strip is used,every pass covers

more area than a

wire cladding

would.

Advantages Disadvantages

Process is

automated andvery fast.

High initial cost of

equipment

Weld requires nofiller metal and is

economical.

Lower tensile andfatigue strength.

Advantages Disadvantages

Heat required for welding is

obtained from chemical

reaction and hence noelectricity is required.

Process is applicable only to

ferrous metal parts.

Process can be carried out

where sophisticated

equipment and power supply

cannot be obtained.

Process consumes more time.

Advantages Disadvantages

Narrow Heat Affected zone. High equipment cost and that

of vacuum chamber. Size of

work is limited due torequirement of vacuum.

Can be used to weld in

applications where the reverseside cannot be welded.

Rapid solidification can cause

cracks in some metals and X-rays are produced during the

process which can be

dangerous.

Advantages Disadvantages

Consistent weld quality. Xenon flash tube heats up

quickly and hence process

cannot be used continuouslyfor long time periods.

Quality of weld comparable to

that of conventional methods.

Life of xenon flash is very

short.
