填角熔接接合喉深區域的計算公式

熔接設計	填角熔接的喉深區域 A [mm ²in ²]
熔接設計	對於熔接全長	對於承載 (有效) 熔接長度
	A = a L	A = a (L - 2 a)
	A = a (H + B)	A = a (H + B - 2 a)
	A = a 2 H	A = a 2 (H - 2 a)
	A = a 2 B	A = a 2 (B - 2 a)
	A = a (H + 2 B)	A = a (H + 2 B - 2 a)
	A = a (2 H + B)	A = a (2 H + B - 2 a)
	A = a 2 (H + B)	-
	A = 2 π a (r + a / 2)	-
	A = a 2 L	A= a 2 (L - 2 a)
	A = a (2 H + B)，A = a (2 H + B - 2 t)	A = a (2 H + B - 6 a)，A = a (2 H + B - 2 t - 6 a)
	A = a 2 (H + B)	-
	A = a 2 (H + B)，A = a 2 (H + B - 2 t)	A = a 2 (H + B - 4 a)，A = a 2 (H + B - 2 t - 4 a)
	A = a 2 (H + 2 B)，A = a 2 (H +2 B - s)	-
	A = a 2 (H + B)，A = a 2 (H + B - 2 t)	A = a 2 (H + B - 4 a)，A = a 2 (H + B - 2 t - 4 a)
	A = a 2 (2 H + B)，A = a 2 (2 H + B - s)	-
