Service TEAM-PATRiA6 Sikap Amati 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 lain Amati faktor faktor yang lain, misalkan kerja keras dan kejujuran, sertasportifitas. Kerapihan dalam
bekerja juga bisa menjadi faktor penilaian.kejujur an merupakan faktor yang tidak ada toleransinya. Setiap welder harus jujur dan
bertanggung jawan terhadap material hasil las lanya.note : Acceptance Kriteria / Syarat kelulusan
hasil las lasan adalah sebagai berikut :Untuk visual tes, tidak bolehada cacat pengelasan berupaundercut, spatter,
incompletepenetr asi. Manik las tampak halus dan tidak terlalu tinggi namun juga tidak terlalu flat/datar (±2-3.5mm
gunakanwelding gauge untuk melihat ukurannya). Below Visual Inspection
Acceptance Criteria : # The crack, 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.# Undercutting adjacent 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) can t exceed 1 inch.# Incomplete Fusion
shall be considered a defect should any of the followingconditi ons 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 of the 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 of
the BT s image exceeds that of the thinnest adjacent parent material) more detailed see Section 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, the indication s maximum dimension shall be considered its
length) more detailed see Section 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 detailedcondition s see Section 9.3.9.2 until 9.3.9.4 and Figure 19 or 20.#
Excluding incomplete penetration due 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 of weld exceeds 2 in. (50 mm).b. The aggregate length of indications exceeds 8% of the weld
lengthuntuk pengujian penetran tes (Optional)accept ance criterianya adalah seperti yangtampak pada gambar
disamping.seluru h standart yang digunakan merujuk pada ASME IX, ASME V dan AWS D1.1.
