Service TEAM-PATRiA6SikapAmati tingkah laku dari welder. Perhatikan betul gaya berpakaian dan sikapselama menjalani proses refresh ini. Bapak bapak yang di site tentu lebihmemahami untuk faktor yang ini.Lain lainAmati faktor faktor yang lain, misalkan kerja keras dan kejujuran, sertasportifitas. Kerapihan dalam bekerja juga bisa menjadi faktor penilaian.Kejujuran merupakan faktor yang tidak ada toleransinya. Setiap welder harusjujur dan bertanggung jawan terhadap material hasil las lanya.Note :Acceptance Kriteria / Syarat kelulusanhasil las lasan adalah sebagai berikut :Untuk visual tes, tidak bolehada cacat pengelasan berupaundercut, spatter, incompletepenetrasi. Manik las tampakhalus dan tidak terlalu tinggi namun juga tidak terlalu flat/datar (2-3.5mmgunakanwelding gauge untuk melihat ukurannya).Below Visual Inspection Acceptance Criteria :# Thecrack, of any size or location in the weld, is not a shallow crater crack or starcrack shall be rejected. The crack is a shallow crater crack or star crack with a lengththat exceeds 5/32 in. (4 mm) also rejected.#Undercuttingadjacent to the cover or root bead shall not exceed the dimensionsgiven in Table 4(Maximum Dimension of Undercutting) and Section 9.3.11#Inadequate Penetration(detail see Section 9.3.1 , 9.3.2, 9.3.3 and figure 13) cantexceed 1 inch.#Incomplete Fusionshall be considered a defect should any of the followingconditions exist:a. The length of an individual indication of IF exceeds 1 in.(25 mm).b. The aggregate length of indications of IF in any continuous 12-in. (300 mm) lengthof weld exceeds 1 in. (25 mm).c. The aggregate length of indications of IF exceeds 8% of the weld length in any weldless than 12 in. (300 mm) in length.And fore more Incomplete Fusion can see on Section 9.3.5 (figure 17)

Service TEAM-PATRiA7#Internal Concavity(Any length of internal concavity is acceptable, provided thedensity of the radiographic image of the internal concavity does not exceed that of thethinnest adjacent parent material. For areas that exceed the density ofthe thinnest adjacent parent material, the criteria for burn-through (see 9.3.7) areapplicable) more detailed see Figure 18.#Burn-Through(The maximum dimension exceeds 1/4 in. (6 mm) and the density ofthe BTs image exceeds that of the thinnest adjacent parent material) more detailed seeSection 9.3.7.1, 9.3.7.2, 9.3.7.3 .#Slag Inclusions(when the size of a radiographic indication of slag is measured, theindications maximum dimension shall be considered its length) more detailed seeSection 9.3.8.1, 9.3.8.2, 9.3.8.3)#Porosity(The size of an individual pore exceeds 1/8 in. (3 mm)) more detailedconditions see Section 9.3.9.2 until 9.3.9.4 and Figure 19 or 20.#Excluding incomplete penetrationdue to high-low and undercutting, anyaccumulation of imperfections (AI) shall beconsidered a defect should any of the following conditions exist:a. The aggregate length of indications in any continuous 12-in. (300-mm) length ofweld exceeds 2 in. (50 mm).b. The aggregate length of indications exceeds 8% of the weld lengthUntuk pengujianpenetran tes(Optional)acceptance criterianya adalah seperti yangtampak pada gambar disamping.Seluruh standart yang digunakan merujuk pada ASME IX, ASME V dan AWS D1.1.
