Other forms: welders
A welder is the worker who joins metal by melting it together. A skilled welder, a pipeline welder, the welder's mask.
The mask is not for comfort: the arc gives off ultraviolet light strong enough to burn the eyes in seconds, an injury welders call arc eye. It is skilled and well-paid work, and underwater welders are among the best paid tradespeople there are.
