This study was aimed to study the general situation of business to compare the financial ratios between life insurance business and non-life insurance business and to study the factors which affected the performance of insurance business. The study results showed that the financial ratios between life insurance business and non-life insurance business were compared it was found that financial ratio of life insurance business was better than non-life insurance business for 6 ratios as follow: Net Premium Return on Assets Total Assets Turnover Policy Liability to Capital Fund Current on Premium and Debt-to-Equity Ratio. As for the study on the factors which affected the performance of insurance business it was found that the performance of life insurance business were affected by the following financial ratios: Return on Investment (0.810) and Dividend Payout (0.354).

And it could be concluded that the difference between the type and the size of business affected the performance differently.

This research was to influence of electrode force affecting the complete of the resistance spot welding. The specimen was mild steel sheet metal has 1 mm. thickness. Then applied the force to the specimen are 1.0 2.0 3.0 4.0 and 5.0 kN. The welded specimens were tested by tensile shear testing according to JIS Z 3136: 1999 and Macro structure testing according to JIS Z 3139: 1978.The results showed that electrode force had affected on tensile shear and nugget size at 95% confidential (P value > 0.05). The low electrode force had increase the nugget heating because it had a high resistance (Q=I2Rt) and increase the gab between specimen. When the resistance increasing so the current flow will difficult to passed that fusion zone will had a high heating. It will affected to nugget seize heat affected zone and mechanical properties decreasing. The electrode forces are complete 2.0 kN. Tensile shear 6.39 kN and Nugget Size 5.83 mm. This data can be applied to be used as process monitoring of resistance spot weld quality.
