Welding and Mechanical Fastener
Welding
Welding is the process of permanently welding two metal components together, either with or without filler metal. It is accomplished by joining the parts' close edges.
Pros
provides exceptional strength and structural performance.
removes the necessity to perforate materials
frequently the method of choice in many situations
Cons
Compared to fixed connections, welded joints are more rigid.
Welds are more prone to fatigue than mechanical fasteners.
welds are much more difficult to remove, replace, or repair than fasteners.
welding poses additional task-specific safety risks
Comparing the inspection method to fixed joints, it is more expensive and complex.
Most of the time, welding is more expensive than fixed joints.
Because welding requires skilled and qualified workers, availability, schedule, and cost are all impacted.
Welds require more time and money to fix in the field.
Different joint configurations, such as butt, corner, edge, lap, and tee-welded joints, are based on how the welded pieces are positioned in relation to one another.
Fastening
Fastening systems are made up of various mechanisms that facilitate the assembly of various materials, guaranteeing structural tightness and flexibility.
Pros
More movement is possible at fastened joints while reducing structural stress.
Installing fastening doesn't require specific equipment or trained staff.
The only special safety concern associated with fastening is working at a height.
They are generally less expensive (including labor and hardware).
may be easily inspected, adjusted, or replaced when necessary
they allow speedier installation in the field
Cons
The installation site requires additional fastening hardware.
Certain applications require the materials to be perforated in order to allow for the fastening procedure.
Fasteners don't always provide the necessary strength since they need to be perforated.
Fasteners can form temporary or permanent joints. Fasteners can be changed, removed, replaced, and/or repaired at any time in the future without causing harm to the underlying affixed components because to the capacity to make temporary joints.

Why Using Fasteners Is Better Than Welding
Lower costs.
Equal strength
Greater accuracy
Easier to finish
Easier to replace
