(2).Competitors receives the test piece and welding material relying on Contest Pass  and lot ticket.

(3).Each competitors should check out whether the test piece has met the requirements before assembly, the test piece can not be changed in general, if there are differences, chief referee decides what to do .

(4).Competitors assemble the test piece at certain place and certain time by themselves.

(5).If the test piece is destroyed during the assemble, competitors can repair them by himself ,and the destroyed test piece can not be changed into new ones.

(6). Invigilators will fill in the Circulation Card for every step of assemble for each competitor ,for the competitors who pass the assemble, the Invigilators and the competitors who pass the assembly will both sign the Invigilators’ name and competitors’ name on the Circulation Card. For the competitors who can not  pass the assembly ,invigilators will inform those competitors to reassemble the test piece, the test pieces can not be used for competition until meet the requirement.

(7).The rules for assembly

a. Time for assembly is 60 minutes.

b. Tack welding should adopt the same welding method and same material as formal welding.

c. All of the test piece should be fixed inside of the front side of groove, fixed-point should be on each side of the test piece, the length of the fixed-point should be less than 20mm.(including 20mm)

 3.Practical competition requirement

(1)Competitors should receive the assembled test piece assembled by the competitors themselves respectively 15 minutes before the competition ,and welding material according to the lot ticket, the competition starts from the order signal, if someone who late 10 or more than 10 minutes should be regarded as quitting the competition.

(2).Competition operation time

120 minutes for gas tungsten-arc welding ,GTAW for short.

150 minutes for oxygen fuel gas welding ,OFW for short.

(3). Electrical tools are forbidden during the competition

(4).Welding machine, welding torch, welding tongs, welding wire and torch which will be provided by a uniform manufacturer, not allowed to bring the tools described above by competitors themselves.                                            

 (5).Competitors should self-provide mask, hammer, manufacturer, rasper, Steel wire brush, abrasive cloth, saw blade, flashlight, Electrode, polishing, monkey wrench(for foreign competitors who will be difficult to bring these tools which can be provided by China Organizer, but the competitors who can not bring these tools should apply for these tools in advance)

(6).The limit of highness for testpiece is 1.5m

(7).Competitors can try the current on the test plate only, not allowed to try the current on the fixture, if do so ,it will be treated as violation of competition rules. 

(8).Should weld on the single side of the test piece.

(9).The direction of flat position welding of test piece should adopt one direction ,not allowed to weld from middle to ends, or weld from two ends to middle, the direction of layer should in conformity with the direction of back welding (except oxygen fuel gas welding)

(10).Other position test piece should be done on the welded bracket in the process of welding. which should not be change site and direction, if the competitors move the test piece for cleaning the seam, it should be put back the original site in the supervision of invigilator, the test piece can’t be taken down without finish, not allowed to mark any thing on the test piece, if there is a violation above happens, the score of individual event is 0.

(11). In the process of welding, the destroyed test piece which the competitors can repair by himself can not be changed a new one,. the surface of front and back seam are not allowed to repair nor remelting, if such violation happens ,the score of test piece is 0. 

 (12). Competitors can state objection when power off or other external influence happens.

(13). Competition time including rest, drink, and go to the bathroom.

(14). After finishing the welding competition, competitors should clean up the super facial of the test piece including welding slag, spatter, but the original form should not be destroyed during the cleaning, electronic tools are forbidden, invigilators will check out the test piece, for those uncleaned test pieces, invigilators have the right to ask the competitors to redo the clean job. For those cleaned test piece ,the invigilators jointly with competitors hand the test piece to certain place, and jointly sign the names of competitors and invigilators on the record of invigilation.

(15).Competitors should obey the fair and equal spirit to take part in the competition, not allowed to destroyed or tear down the competition provided facilities, if such violations happened ,all of the score will be canceled for the competition violator.
