| 31. | In some processes ( for example, arc welding ), electric current is directly applied to the workpiece.
|
| 32. | The electrodes employed for twin-carbon arc welding are approximately of the same diameter as the workpiece thickness.
|
| 33. | In open-air applications, such as construction and outdoors repair, shielded metal arc welding is the most common process.
|
| 34. | Although spot welding does not generate UV light as intensely as arc welding, eye protection is nevertheless required.
|
| 35. | Among those who collaborated with the company were Karol Adamiecki and the pioneer of arc welding StanisBaw Olszewski.
|
| 36. | This process is being replaced by gas metal-arc welding, mainly because of the availability of inexpensive inert gases.
|
| 37. | FCAW was first developed in the early 1950s as an alternative to shielded metal arc welding ( SMAW ).
|
| 38. | To supply the electrical energy necessary for arc welding processes, a number of different power supplies can be used.
|
| 39. | Other welding methods, like shielded metal arc welding, are extremely versatile and can weld virtually any type of joint.
|
| 40. | Manual gas tungsten arc welding is a relatively difficult welding method, due to the coordination required by the welder.
