Section 408.11205. Definitions; P to W.

(1) "Press welding machine" means a machine  that  utilizes   2 platens, 1 of which moves toward the other during the initial part of the machine cycle. It does not provide  welding   pressure.  After  1   of  the platens has moved to a stop position, the welding pressure required for the welding operation is applied by 1 or more air or hydraulic cylinders.

(2)   "Psig" means pounds per square inch as measured by a gauge.

(3)   "Resistance welding" means the joining of metals by the use  of   heat generated at the joint by the resistance to the flow of electric current and by the application of pressure.

(4)   "Soldering" means a process of joining metals without melting them using a filler metal melting at 800 degrees  Fahrenheit,   427   degrees centigrade, or below.

(5)   "Spot welding" means a form of resistance  welding  in  which   the current and pressure are restricted to the spot of metal surfaces directly in contact between the electrodes.

(6)   "Storage" means the storage of filled or empty cylinders not in use.An oxidizing and fuel gas cylinder or cylinders used as a unit shall not be considered to be in storage.

(7)   "Water capacity" means the weight of water, as related to liquefied gas, of a volume equivalent to that of the cylinder.

(8)        "Welder" means a person capable of  performing   a  manual  or semiautomatic welding operation.

(9)   "Welding operator" means a person who operates a machine or automatic welding equipment.
