||A review of systems used in the USSR to control welding fumes produced during the assembly of agricultural equipment. The systems fall into 3 categories: those that are independent of the tool or workpiece; those that are incorporated into accessory equipment; and those that are incorporated into welding tools themselves. The categories are illustrated respectively by a hood with a circular slot that can pass 2000-3000m3 of air per hour; a tilting cradle that has internal air passages and slot hoods at intervals along its length; and an electric welding tool with 2 concentric tubes around the electrode. The cradle can handle objects up to 6m in length, and can exhaust 7000m3/h. The welding tool is connected to a source of carbon dioxide and to a vacuum line; the carbon dioxide flows out of the inner of the 2 concentric tubes to form a curtain around the welding arc, and is sucked up through the outer tube along with entrained welding fume.
