Scope,This standard specifies method of hardness test in weld heat-affected zone of,a steel by means of taper test specimen deposited on by arc welding and of obtaining,relationship between cooling time from 800 ℃ to 500 ℃ and maximum hardness,hereinafter referred to as the "taper hardness test".,2. Test Specimen,2.1 The shape and dimension of test specimen shall conform to Fig. 1 . When,original thickness (t) of test material exceeeds 30 mm, it shall be machined cut to,30 mm on one face, and when the thickness is under 30 mm and over 1 5 mm, it shall,be left in original thickness .,2.2 The side faces of the test specimen can be left as flamed cut.,3. Welding,3.1 Each two of arc strikes, short beads and long beads shall be deposited,respectively on the position as indicated in Fig. 1 . The long bead shall be deposited,to its required length by each one stick electrode without interruption, commencing,from the thin part of the test specimen to the thick part.,3.2 The order of depositing art stricke and beads shall be by ①,?,②,②,⑧,④,as indicated in Fig. 1 , letting the test specimen cool down in the air to the temperature,approximately below 40 ℃ before depositing the next bead. In this case,when the test specimen is less than 30 mm thick, the short bead shall not be deposited.,3.3 The covered electrode shall, as a rule, be of 4 mm diameter low hydrogen,type after required re drying treatment and of the quality suitable for the test,material.,3 .4 The surface of the plate before welding shall be left in black state as manufactured,carefully removing by suitable means the grease, rust, scale and moisture,which will be harmful for welding ,3.5 The test specimen shall be supported on both ends of the longitudinal,direction allowing a sufficient air space under the reverse face.,anniラハ。Vxic j+cndard,Copyright Japanese Standards Association *,Provided by IHS under license with JSA Licensee=IHS Employees/1111111001, User=Wing, Bernie ホ " .,No reproduction or networking permitted withoutjicense fromJHS}jQ(^ of Maximum Hard II Notjor^ Resale, 03/10/2007 19:11:27 MST ■ Af f TjOnA,;JIS Z*3115 73 , M533b06 0D7L521 3 ■ g,2,Z 3115-1973,3 .6 The welding condition shall, as a rule, be as indicated in Table 1 .,Table 1 .
